wm 5.0 totom & 5.100 & Altina GPS

with tomtom 3.0 it was simple to connect with tomtom 4.0 it was again simple then came tomtom 5.0
had to select wired gps and then chose com port 6 with tomtom 5.0 with wm 2003se. with wm5.0 its all different cant get it to synch with my gps any help will be great. im sure there will be a lot of people strugglign with this

Same problem here but using a Pharos 360 with the Bluetooth docking station. With WM2003SE Tom Tom shows a lot more com ports. It used to have Com5 and Com6 and the bottom of the configuration screen. Now it only has Com1 Wired connection, Com2 and COm9.
When pairing the GPS to an outbound serial port you can not use com9, Com2 or Com1. If you pair the GPS to new port like com6, Tom Tom still does not offer com6 as an option.
So I figured you had to use the GPS control panel item to map another Com port to the actual GPS com port. But still no joy. After creating a new software com port it still does not show up in Tom Tom. If you use one Com2 or Com9 that Tom Tom does have options for, it does not connect.
Anyone got this working??
Shawn

Please check your PM.
Thanks,
Darren

solution found for the above
go to bluetooth and pair the gps with the phone. enter passcode if required then click on new outgoing port and then select com port 6.
open tomtom then select configure gps then select other buetooth gps. you should now see com port 6. select this and everything should work now.

That does not work for me. Once I pair my GPS and assign it a com port, the com port will NOT show up in the Tom Tom GPS configuration screen.
Shawn

tomtom
need to ensure you enable the serial connection when it asks you. for me it worked on com 6 and should be same for you no matter wat bluetooth gps you are using as it says this on tomtom website. instead of using wired gps like in 2003se we need to use bluetooth gps option and it should work. seems to work fine for me. do a breakdown of what you are doing cos we may find something i am doing that you are missing out or something you are doing which is wrong.
by the way i have beams turned off and i have not fiddled with com ports on the gps setting icon in settings menu. the application and hardware port have been set to none. we just need to apply the gps port to com 6 upon creation of partnership

Thanks for the reply
This is what I am doing.
Settings->Connections->BlueTooth
On Mode tab. Turn On Bluethooth
Click Device Tab
Click new partnership
Pharos iGPS-BT shows up. I select and say next
I check the serial Port service and click save
I click on Com Ports tab
I click on new Outgoing Port
I select My GPS and select Com6
I have tried with the "Secure connection" on and off
Click Finish
Now the comm port tab shows
Pharos iGPS-BT (COM6)
New Outgoing Port
New Incoming Port
Click Ok to close the BlueTooth manager
Click X to close the settings window
Run Tom Tom
Click on the GPS Bars to get to the status summary
Click on the bars again to get to GPS Status
Click COnfigure
Select Other Bluetooth GPS
Press Continue on next screen
Now all the shows up is
BT UART
COM2:
Serial Cable on COM1:
COM9:
Ir on COM3:
So I can not select Com6 as it is not in the list.

i have the problem....
can,t anyone welp. pls

think i have a solution
slammers et al,
switch off 'Receive all incoming beams' in Settings, Connections, Beam.
in Settings, Connections, Bluetooth, Services select Serial Port - in mine 3 are ticked:
Enable service
Authentication(Passkey) required
Encryption required.
click Advanced, Inbound COM Port is 5, Outbound COM Port is 6.
switch on your bluetooth GPS receiver.
open Bluetooth Manager and double tap your GPS receiver, if it's not in Bluetooth Manager then pair the device and create a serial connection by clicking New, Explore a Bluetooth device, select your device to make a serial connection shortcut.
start TomTom, go to 'Change preferences', Show GPS status, Configure, select 'Other Bluetooth GPS' and select Serial port 6....click done....in the GPS Status window you may see that it is connected....if not do the next step.
click done, exit application.
soft reset device.
switch your bluetooth gps receiver off then on.
start TomTom, leave it for 30 seconds....it should connect to your GPS device...if you have the older TomTom GPS receiver you'll be able to tell that it's made a connection by the constant blue light being displayed on the gps receiver.
if you have no luck with selecting 'Other Bluetooth GPS' try selecting 'Other Cable NMEA GPS', choose GPS baud rate 4800 and then 'Bluetooth Serial Port 6' in the TomTom configuration screen.
i know it's a bluetooth device but this has been a problem prior to version 5.10 of the tomtom software and people have had success using this option and connecting.
i've had success with a few different configurations and have helped a few people get theirs working.....also there is a claire on this board who i went through a painstakingly long back an forth post with and i'm still not sure if she got it working....but i've just learned how to get mine working where it turns on the bluetooth automatically and switches it off also...and prior to this post i had it connected using the 'Other Cable NMEA GPS' instead of Other Bluetooth GPS....so good thing i turned it on and messed with my config while trying to explain how to modify yours.
good luck.

i dont have this opction on windows mobile 5 decoy 7....

you dont have that option?

no... mobile 5 have the BT like qtek s100.. very simple.... :shock:
but finely i have put on work the bt-338 on mY BA with tom tom 5
i do this:
seting-connections-bt then i partnership with gps
next
setings-connections-bt-com ports and make outgoing port with gps (com6)
setings.connections.bt.com ports and make incoming por (com7)
next
go to gps frome wn5 and put com7 in "software" live the menu of hardware as "none" and 4800 and ond the 3 windom put on
then opem de tom tom and open de pgs configuracion and use "other bt gps" and use the port com6...
work on me :lol: :lol:

GPS Help Please!!

Hi,
Just bought a new Nokia LD-1W GPS and trying to connect via bluetooth.
How do I pair the two devices and how do I create a incoming/outgoing com port to work with tomtom.
I've searched the forum & found nothing:-(
Please can Someone post a step by step process please as it's all confusing.
Anyones help will be gratefully appreciated.
Yohanson

Are you using this with the phone on WM2003SE or WM2005? - then I should be able to assist - Mike

Thanks for replying so fast. I'm using it on WM2003SE.
Thanks

Turn on Bluetooth on the Phone, Turn on the GPS unit.
Go to Bluetooth Manager.
Press Bluetooth symbol on the bottom task bar.
Scroll to the bottom of Bluetooth Connection Wizard.
Select Explore a Bluetooth Device.
after a while you GPS unit should become visable, select it.
On the next page select SPP Slave, then press Next followed by Finish.
On the Bluetooth My Shortcutspage (which sould show automatically at this point) Tap & Hold the GPS icon, from the pop-up select connect. You should get two small green arrows on the GPS icon showing it is connected.
All Done, all you are left with is to configure TomTom, run it up then go to prefferences/ GPS page, select "Other cabled NMEA device" (yes I know its a BT unit but trust me), set the Baud rate (check for this with the supplied info from the manufacturer, or web site, then on the last page go for outgoing Bluetooth comm port 6 (It helps if you put it in landscape mode for this bit as you can see the port numbers this way) - tke it all outside and wait for upto 30 mins for a lock, after this it should be far faster. Sorry for the edit, but didn't add the TomTom bit in first time!!
Mike

If you want any further tips on configuring your TomTom, adding speed cameras, voices etc. try www.pocketgps.co.uk that is set-up for GPS rather than phones (I use both this site for the XDA technical bits) and the other for GPS/ TomTom - Mike

Thanks mike for your thorough step by step guide, but my main problem is making a new bluetooth com port so tomtom can see it in the GPS settings.
Do you know how to access them in bluetooth setting to change outgoing and incoming ports?
I'm lost:-(

At which point following the above set-up does it not offer the selection I have stated to take, I know this works with my BA as deleted the GPS unit and started from scratch just to make sure? - Mike

XDA Exec and Holox BT-321 GPS Receiver

hi there
new to this forum which looks very interesting. Hence asking answer for a problem.
i have bought a Holox BT-321 gps receiver which is blue tooth enabled and i am trying my xda exec to recognise it. aftre turning both devices on xda can see the receiver but puts a yellow question mark before its name.
when turn the gps software on ((Medion Navigator) it does not recognise presence of the gps receiver.
i have great hopes that out there some one does know the answer to this.
to me it appears a software conflict as xda can not install this receiver.
i have tried O2 but they politely refused and asked me to contact gps receiver makers who in turn say the receiver is working fine!!
i was about to pay for a software pathway for sale at ebay but it had been banned by the ebay.
so help please
mohammad asif

Assuming that you did set a port for it (not sure whether it's incoming or outgoing) on the Exec for the GPS unit, you'll probably have to set the port to see the GPS unit on the software also.
That's how I got my GPS unit to work with my software. Please note that the software and the GPS unit that I'm using are not the same as yours. So results might vary.

I too am having exactly the same issues with the Holox 321 and o2 Exec. If anyone has had success pairing a using these two devices and can post a step-by-step walkthrough on how to do it I'd be very grateful.
Thanks.

MDA Pro and BT321
I have got exactly the same problem. It seem that the bluetooth works but the GPS receiver is not recognised. I was thinking of it could be missing drivers or something along those lines

I'm seeing a trend...

hi all,
My m8 has one of them on an XDA2i and the only way we could get it working with TT5 was to set it up as other NMEA GPS on com 6, that did the trick
hope that helps

Thanks BBD, that may help. Trouble is though, I can't even get it to pair correctly. The Exec seems to go through the motions, but the blue light that's meant to flash whenpairing is successful just stays solid.
I also get the question mark appear next to the device in the list of BT devices. What OS is your friend using? WM5 or PPC2003?

hi m8,
he is using WM2003SE, he two has the question mark beside his device I think that just means it does not have a Windows Certificate nothing more, just cheked my TOMTOM device has the question mark too and that works fine
Matt

hi,
just double checked and this is how it worked, pair the GPS receiver up, then go into TomTom and use the NMEA devices with baud rate of 38400 then select bluetooth on com6 and bingo bango your off
cheers
Matt

I think my problem occurs before TT5 is even invloved. From what I've seen WM2005 is very different from PPC2003 as far as BT goes.
I search for a new device and the BT-321 is seen as normal. I select it then enter the sec. key; ok so far. then I'm ask what services I want to use (only "serial port" is available). I select this, then finish. At this point I expect the blue BT light to start flashing telling me I have a successful pairing, but it stays solid. I have tried creating a new outgoing port, but no change.
Until I can get a successful pairing my BT port doesn't appear in the list in TT5, so I can't select it.
I wish I could find someone who has successfully paired these two devices...

Bump.

I can pair my mini s to the bluetooth reciever, but not tt5
i have paired my bluetooth reciever with my xda mini s but when i go to select it in tt5 none of the comports correspond with any i can pair the reciever with. I have installed bttools but this hasnt helped either. someone suggested i needed to build a com port but i dont know where to start, and they also said its because its an xda that theres comport problems, i donubt im the first one with this issue. i pray someone can help me out, would be much appriciated.
email [email protected]

Same problem on my Wizard with the Gpslim 236. However, my fiend brought over his rikaline last night and it worked very quickly. Go figure. I think I'll be exchanging today.

I got the BT321 working with the Universal no problem.
It paired okay, gave me the COM Port option which I took, showed the icon with ? on it.
Going to the COM Ports tab, I created an outgoing port (COM0).
In TT5.21 (I think you need the latest version of TT5) I selected COM0 and after a while it found it no problem..

paring xda exec + gps holux 236
i did pare the 2 after updating tomtom to 5.21 free from tomtom web site then u get com 8 were u can set the outgoing port from the xda ,voila

I have XDA EXEC and have successfully installed the Holux BT-321 Bluetooth GPS. It runs perfectly with a number of GPS applications - so I know the port/Bluetooth configuration is ok. I had to choose an unused com port (0 or 4 work fine). (Ports 1,2,3,6,7,and 9 seem to be already used by the XDA EXEC - so could not be seleted).
BUT (going back to the first post) Medion Navigator (4.2) does NOT recognise the new GPS port. Instead it has options to select ports com1,2,3,6,7,9 but not the "new" port where the GPS is actually configured!
Does anyone have any ideas about this?

After several hours trawling forums and trying lots of things here's what worked for me on an XDA Exec running WM5. In fact I was shocked when it worked! In return for this can someone please think up the next thing after Toothache! The WM5 bluetooth connection thing could also do with a re-write - as could the WM5/XDA Exec instructions/FAQs/help, etc... on BT:
If your aim is to get TomTom working AND you're using a non-TomTom BT GPS, try this (the TomTom GPS seems to install itself without much problem):
1. Pair the GPS with your device BEFORE installing TomTom, because the GPS port needs to be already setup on your device for TomTom to recognise when installed.
2. Then install TomTom
3. Launch the BT connection thing in WM5. Make sure the BT is discoverable (first tab). Select 'Security' tab and ensure 'Authentication (Passkey) required is checked.
4. Go to 'Devices' tab and select 'new partnership...' The pairing thing should find your GPS and will then ask for the passkey - select next WITHOUT entering anything even if there's a passkey. If you enter the passkey now you will not get step 5 which is a crucial milestone.
5. The device should now ask if you want to add the GPS to your list, select yes
6. The name of the GPS is shown. Ensure 'serial' port is checked and hit next
7. You will be asked for the passkey again - enter it this time
8. At this point the GPS may look like it's not paired. The lights may flash as if unpaired. You'll also get a question mark icon next to the GPS in your list. Not to worry.
9. Select 'com ports' tab and select 'new outgoing port'. You should see your GPS listed. Select it and hit next. From the list of ports select COM8. Make sure the 'Secure connection' is UNCHECKED - otherwise you'll be pairing everytime you start TomTom! Select Finish. You should see your GPS (COM8) listed in 'COM ports' tab.
10. Turn off 'device is discoverable' (first tab).
11. Now install TomTom. Having installed the GPS as above, TomTom will now know about COM8 i.e. where your GPS is to be found. If you hadn't done that first there would be no COM8 and no GPS connected to it as far as TomTom is concerned.
12. Turn on the GPS
13. Launch TomTom and go to 'preferences/ GPS Settings'. Select 'configure'. Select 'Other bluetooth GPS'
14. You should get a list of ports and with any luck you should see 'COM8' - select it and hit 'done'.
15. I think at this point the GPS page in TomTom came alive, or maybe I had to restart TomTom - can't remember. And it works thus far!
Toothache - what a palaver!

BT/GPS Problems
Hi,
I have a program that can sort out the com port problems between the bluetooth and gps software.
I have included the program as an attachment, just unzip it into your PC, make sure you reboot your PDA, sync your PDA to the PC and run setup.
Problems solved.
Cheers,
John

Hi,
I`m a new member.After installing your litle tool i can`t start this application and also can`t find it under programs or anywhere else?
I`m using a T-Mobile MDA Compact II with WM5 latest ROM, a Holux BT321 and TomTom6. `have expierences with BT and XDA`s using TT5 for a long time.
After upgrading to new devices and new sw i have the following problems:
I can connect the BT321 as a BT Mouse and get a good signal.Using TomTom6 the navigation works with a delay of round about 100 meter. I`m looking for a resolution to connect the BT321 via the NMEA Interface.

TomTom & Bluetooth GPS
Hi there,
I am just guessing but give it a try, as i am using a cradle based GPS device bcs i wanna use the bluetooth headset as well during drive.
1. Try to first pair your Bluetooth GPS device with ur phone.
2. Once pairing is done, start TomTom
3. Goto ""ChangePreference->ShowGPS Status->Configure->Other Bluetooth GPS.
(Com1 is for the wired NMEA GPS device)
Your phone must within the connection of ur Bluetooth GPS device, now try BLUETOOTH SERIAL PORT Com5.
Try if its help

Hi Sidd,
I have tried that. The problem is that the phone won't allow me to connect to any other port than 8, 4 and 0 and in the Tom Tom menu there is no option of chosing those ports.
Thanks for advice anyway.
Rob

Hi Rob,
Make sure ur Beam is OFF
Start->Settings->Connection->Beam
MUST be UN-TICKED.
(By the way I am in London, where r u?)

One more idea :idea:
1. Pair ur GPS
2. Once pairing is done, switch OFF ur phone's bluetooth (bcs ur phone is engaging the com ports), do not switch OFF ur GPS.
3. Now soft reset ur phone, make sure the Bluetooth is still ON
4. Start TomTom, see if there are more ports now. Try 5 or 6
GoodLuck
Sidd

Hi Sidd,
Thanks for another piece of advice but unfortunately that did not help either My Beam is OFF and I've tried the way with soft reset but that did not work either. I am getting desperate here
My device is XDA Exec and I am using (or at least trying to use) a BT GPS receiver with it. After pairing devices everything seems to be all right except the fact that I am not able to assign any other ports than 0, 4 and 8 to be used with GPS receiver. As I mentioned earlier there is no option of choosing any of these ports in TomTom5 software with the only options as follows:
qct data interface
RIL on com6
com7
serial cable on com1
Ir on com3
Maybe you know any ComPort Manager software I could use to assign the Bluetooth connection to a specific port?
As far as my location is concerned I am in Hayes - that's Zone5 near Heathrow airport.
Cheers,
Rob

Which TomTom u using, is it the legal version or ****. Do u wanna meet, so we can try my version?
I am in Pinner, do u drive?
Sidd

Hi all,
I have exactaly the same message and problem.
Natan69
Please if you found a solution help me. i installed my tom tom today so I expect that you may solved your problem by now.
please help me you have been in this situation and you know what i am through.
Thanks

Hi all,
I had exactly the same problem than you guys...
But first of all I couldn't even install tomtom5.
The version 5.0 crashed in every attempt to install and version 5.21, simply crashed when choosing the map.
Well, I'll try to put every step I did to get it working.
First of all, had the BT GPS paired with K-JAM and set new outgoing port COM6 to it. (in my case I only had COM6 or COM7).
1 - With the full copy of 5.0 version on HDD, replaced setup.exe with the one from the 5.21 update (this allowed the setup for 5.0 to run, and is the one that has the gps.cab file);
2 - Updated with version 5.21;
3 - Copied the map to \Storage Card\
4 - In Windows created the file CurrentMap.dat using Notepad containing: & \Storage Card\XXXX-Map\ (where XXXX is the map name. the final \ is mandatory);
5 - Copied the voiceXX.cab to device and run it;
At this point I was having the same problem (both COM6 nor COM7 appears in tomtom)
6 - Downloaded the GPSInfo_WM5.zip attached here and installed it;
7 - Executed this program, configured it to COM6 (port I had configured BT GPS to work with) selected the correct baud rate (very important, it's on the user's manual of the BT GPS) and click Start GPS to check it's response to the program;
8 - Click Close GPS so that the COM port was not in use;
9 - Started tomtom, edit the settings and chose Other Bluetooth GPS.
Now the ports COM6 and COM7 was there!!!!
10 - Chose COM6 and in 10 seconds tomtom was trying to aquire satelites.
I hope this helps you all. I spent weeks trying to make tomtom work and I got it working yesterday.
BTW, excellent forum. If it wasn't this forum (and another one only in portuguese I was still mad with this thing.
Good luck in your adventures.
Cheers,
Nuno.

Bluetooth GPS going in the bin soon

I'm hoping for some instructions in "laymans" terms here, I'm happier playing around with cars than tapping away on a PDA!
Got an XDA 2 for work data communication, and just had the bright idea to buy a Bluetooth GPS BT74 receiver and TomTom6......and can I get it to comunicate!! Read plenty on here, but theres plenty of talk of Bluetooth device manager , bluetooth shortcut icons, comm port etc which I can't find. Only settings for Bluetooth are Start/settings/connections and the Bluetooth icon on the bottom right.....where am I going wrong!!!!!!!!!!!!!! HELP..............going back out to the garage to play with some spanners for an hour or so ......to forget "Bluetooth" and "PDA"
Andy

i know some people have issues with this but i got a generic AUD$60 gps bt unit last night for my jam,
i had it working within a minute using tomtom 5.
just did the usual pair then launched tomtom and away it went,
get a free program called VisualGPSce i ran that first to make sure the phone was seeing the gps, it also shows the number of sats it can see and the number it connects to.

visual gps
Would you have the visual gps programme. if so could you post it ass an attachment to direct me were to get it?
Thanks

try to get the TomTom gps unit - it works out of the box with no configuration at all.

you need to set the gps up in the tomtom application select other bt gps and then slect com 5

It's been more than a month so I can only hope you got it working. But if not, here are some generic instructions. I don't own an XDA2 or BT74 (I bought the BT-359)
1. Turn bluetooth on on your XDA
2. Turn your GPS on and put it in pairing mode (if it requires a pairing mode, the manual will tell you if it does, if not, step 3).
3. Have your XDA 'search' for bluetooth devices. It should find the device (sometimes it calls it 'unknown' for a few seconds) and ask for a pin code. Usually it's 0000, again, check your manual.
4. Once they're paired (ie the XDA can see it) it may ask you what services you want, select 'serial port'. Then you have to somehow create an outgoing serial port. It may do this when you tell it you want to use the serial port or you may have to select 'new outgoing port. Pick a port number.
5. Now look on the CD that should have come with it and run a tool on your PDA called 'GPSINFO'. Plug in the com port number and whatever the manual tells you the baud rate should be and verify connectivity. If it can't find it at this point, stop and go back.
Next configure tomtom, install tomtom, run tomtom, go 'configuration' and setup your GPS as 'other gps' and plug in the above mentioned settings. Easy.
