TMC to USB Port (for Chinese GPS) - Upgrading, Modifying and Unlocking
Dear All,
I would like to share my experience in this TMC project.
Recently I bought a Chinese GPS 100 unit to connect to my JVC KD AVX40
This has an av out in 320x240 and JVC has an AV in.
You can control the unit via touchpad.
It works correctly to my unit so I decided to get a TMC for this product.
This unit has One USB port which is in Host mode.
So Put a normal USB hub on it and it worked well with Pendrive and External Mouse
Next step, I got a FTDI USB to Rs232 device.
It has FTDI 232BM chip for UART connection it's very important to use chip like this , because of the windows ce driver
I've opened it and I removed chip called SP213EHCA.
In every RS232 there are 2 chips on the board. One is for USB to UART , and the second is for Uart To Rs232.
Because the every TMC receiver uses TTL communication which is working on 3.3v I need to "convert" the unit to USB to UART TTL only.
Obviously you can build a small circuit for this communication, but for myself it was easier to use this solution.
After I removed the Rs232 chip.
Datasheet Page 5 for picture of the pin outs.
You can download it from the FTDI website
The Tmc Receiver pin out is :
Pin definition:
Pin1 Vcc: 5V +- 10%
Pin2 TX: 3.3V TTL level, TMC data output.
Pin3 RX: 3.3V TTL level, receive commands.
Pin4 GND <-- It's not ground It's 5V !!!
Pin5 GND (for mini-USB only)
I soldered a mini USB mother type connector to the chip legs:
PIN2 goes to chip leg 24
PIN3 goes to chip leg 25
PIN5 goes to chip leg 17
So after this I connected the Royaltek TMC unit to my "hacked Rs232" board.
I put the "hacked rs232" to hub and I used a USB mini usb cable for power the tmc unit, so I connect the cable to hub and after that to the tmc.
After this I used this driver for windows ce 5.0
You can download it from the ftdi web site
I have to use mortscript which copy a self made reg file to the registry and copy the ftdi dll to /windows/ folder
Reg:
REGEDIT4
[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\1027_24577]
[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\1027_24577\Default]
[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\1027_24577\Default\Default]

[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\Default\Default\255\FTDI_DEVICE]
"DLL"="ftdi_ser"

"Version"="1.0.2.11"
"ActiveSyncSetting"=dword:0003e880
"LatencyTimer"=dword:00000010
"DeviceArrayIndex"=dword:00000000
This reg file is directly uses COM PORT 1 (It was free in my device )
After this I created a very small circuit which holds the usb power for 20sec
parallely my reg and driver is installing in this time.
When I reached 20sec My Hive based Windows Registry will recognize the FTDI device and there are no pop up meassegas appear ....
IGO recognized the TMC device hardware
The reason I write this how to , because I read so many forums ,and web pages to find a solution for this , but i didn't find anything.
GNS is providing a TMC receiver for CAR PC but with a prolific based USB to UART chip, and the ARM based cpu is not understanding the driver
Ough I forget the tmc receiver what used:
Royaltek RTA-3000

I got the same JVC stereo, how can I unlock for multizone DVD? Thank!
If i understand it correctly that you mean, you want to unlock the dvd region limitation.
I didn't unlocked it, but the main problem, that the unlock lock status is came from the dvd FW, which is not possible to reach it, via this unit. I searched for the web, and JVC also, for some FW update. There isn't any. So from my side i say it's not possible in easy way.
I have tested this solution and since half year aho its working fine under -20 to +50 so it is a solution.
Sent from my GT-I9000 using XDA App
Compatibility
Also tested with FT2232H
This soultion is working , only bug that because of the dual uart the windows device pop up a notification for the second uart driver.
Also working.
Not working with Moxa chip.
Not working with Prolific PL-2303. ( Because the driver for the chip is not going to get open com port in wince 5 :S )
It seems that the only solution is the FTDI chip.
I've made a test with bluepanter and Wayteq and a very old Blaupunkt.
Solution is worked when I changed the usb mode to Host in wince.
It's seems for the blepanter and the wayteq it make not so much sense bacuse you could buy their original accessories.
For the blaupunkt is okay.
Also this could be okay for the 1-2 din chinese gps. Needs to be tested.
Reception improving
I had issue with the tmc reception.
So the solution is make a fm Y cable, and share the outdoor antenna to the head unit and to the tmc receiver.
After the installation, I realised that the reception was not so good, because I miss calculated with the phantom power to my roof antenna, after the phantom power installation everything went fine.
I got reception where I never had it before. TMC news downloading time improved as well.
Take care with the phantom power because it could kill the TMC receiver, use only one way adapter !
hi,
many many thanks for you thread...i had some questions...
i have bought an Dynavin DVN-MC2000 and this unit is without TMC but it have an GPS-In Mother-Usb cable...i think this goes directly to the wince5.0 system.
Where did you buy your RT-3000 and do you have the complete name of the FTDI Modul?!
Maybe we can develop a solution together i could make fotos from my open DVN-MC2000 if it helps
Maybe a ohoto would be great.
I bought the tmc unit in hungary in an avarage shop.
About ftdi i had one in my work desk. But it doesnt matter the meaing is it should any type which is supporting from the wince ftdi driver side. See ftdi web.

Hello all!!
I've been reading the post and I have to congratulate you, very interesting!
If you do not mind I'll use this thread because I want to ask you a question, I haven´t found any response in any expert forum.
I have a problem with my car radio. It is a chenese radio with GPS and TMC integrated.
From the beginning the TMC worked correctly but It had problems with the GPS. It didn´t work properly (may be the driver was wrong or it was bad installed on the WIN CE5). The provider din´t give me a solution and I found a forum in France. There someone sent me an European WIN CE 5 ROM with the GPS installed a working properly. The problem is that this guy didnt have any ROM with the TMC driver integrated and now I dont have it installed.
My actual state is: WIN CE + GPS HW (installed and working) + TMC HW (not insalled)
My question is:
How could I install the TMC in my radio WIN CE5? The HW exists but my WIN CE 5 does not have the drivers and of course the IGO can not find it.
Thank you very much!
pd: sorry about my english!!!

From the first i need to know what kind of tmc chip do you have. Royaltek/GNS and after that we can get closer to the problem. Qhit the upper sokution you can put in the driver if we will figure out the chip manufacturel.
Sent from my GT-I9000
I am sure that the integrated chip is GNS tipe.
The only thing that can hapen if we install a wrong driver is that it would not work, wouldnt it?
But the other things would work good...
thank you!

I found something maybe from your IGO8 folder is missing one file called gpstmc.dll
Check this forum
http://www.mobilepassion.org/viewtopic.php?t=2355
I will check it.
Anyway I think that I need the driver for TMC receiver. I have the HW but it is not installed. Do you know were could I find TMC drivers for Win CE 5? with them the problem would be solved-install and the IGO would take it automatically (I had it installed the first time, but the GPS didnt work).

adding bluetooth to xda 1
Hi all, I am working on adding bluetooth to the xda 1. I have searched on the net for a serial BT board because usb is not a option. Turns out that almost al BT boards found in the cheap usb dongels have serial / pcm and usb connections on it. the best manufacturer I could find is CSR they stack almost everything in a smal package and there is lots of info on there web site. Since I am mainly a hardware guy I am a bit stuck on the software side. I am looking for a way to make my xda talk to my BT board. I was thinking of reassigning the bt com port (ppc 2003) to my external com port through the registry, but which key to attack for that ? Perhaps trade in my IR port (dont use it) this will voidyour warranty but I dont have any. Also finding a piece of BT software to drive the board is hard to find, i Got some from a CF BT card. but no luck so far. Any body who can help me with this ? thanks in advance.
TMC and Artemis
Anyone tried TMC Demo Program from Royaltek http://www.royaltek.com/index.php/component/option,com_weblinks/task,view/catid,46/id,3/ or GNS TrafficCompact from Dantotec http://www.dantotec.de/shop/gns-trafficcompact-tmc-software-fuer-pocketpc-p-10808.html it would be great to know the COM port of the internal FM radio (if it has a com port), or a possibility to get the rds data from the radio to a COM port, for use with TMC compatible software like Navigon.
Tried I've tried it with the first program but it needs a com port and i don't thinkj the p3300 has linked its radio to a com port.
Maybe someone could try Route 66 in the newest version. It supports TMC via RDS (update on www.66.com) people in the Eten forum also said that TMC even with the new glofiish x500 doesn't work and that this is a problem with the navigation software that doesn't support those fmradio chipsets. but the newest route66 shold work. maybe we have to wait until navigon6 pda will be released, i think navigon will have support for the newest chipsets in their newest software. or try the route66 software.
1 question and i hope my head isnt took off here but wat is tmc?
Exec Man said: 1 question and i hope my head isnt took off here but wat is tmc? Click to expand... Click to collapse Traffic Message Channel, it provides information on accidents/ hold ups etc via FM radio. I doubt this will work via the Artemis, the Route 66 web page does list a couple of suitable TMC units to work with the latest update, the biggest problem is the need to have the earphones plugged in to act as the aerial, couple this with poor reception (the audio plays well on strong stations, but drops out on weaker ones). The other problem I now have following the upgrade to the latest R66 is messed up menus, tech support later today! - Mike
How to Programm the GPS?
Hello, does anybody know how to programm the GPS Modul? I tried to change GGA to 1. Can somebody help me?
Have a look here ... www.franson.com They sell a module which you can easily program to with visual basic. They demo programs work without a modification. With Visual Studio you can start programming in a hour or so, after having had a look at the samples.
I think meer wants to adjust the SIRF-III-Chipset, which is used in the Orbit. Most tools "Sirfdemo" etc. wont work on the Orbit. :-( I'm searching for a tool which can toggle SN (Static Navigation) off on this device.
Hi, I tried almost everything to program the internal GPS receiver of my P3300, but did not succeed :-( First, I tried to get direct access to the hardware GPS port (COM 3), but failed to open this by any way. Eventually, I even sent my device into the Boot-Loader mode, redirected the GPS receiver to the USB port by using the GPSRouting command and connected via USB the SirfDemo 3.81 program. Results were very strange: Using GPSRouting without a parameter gave me binary output data which SirfDemo was not able to handle. Starting the the receiver at 57600 baud (by using the command "GPSRouting 57600" gave me NMEA output, which SirfDemo was partly able to handle. Some messages appeared correctly in the debug window, but most output of the GPS receiver resulted in SirfDemo in error messages. Really stranges! I DID NOT FIND ANY WAY TO SWITCH TO SIRF MODE, which is necessary to program the internal sirfIII chipset. I finally gave up and hope that one day HTC will surprise us with a nice tool to enable/disable Static Navigation and SBAS mode. GeenZ
Have you tried using COM4 which is where the actual GPS receiver can be found? - Mike
mikealder said: Have you tried using COM4 which is where the actual GPS receiver can be found? - Mike Click to expand... Click to collapse Of course, trying to use COM4 was my first attempt. However, COM4 is the output port of the MS GPS Intermediate Driver (GID). This is a software com port, which seems to be not the best implementation of a virtual comport splitter. There are a couple of programs out there, which have serious problems with the GID port, but do work with other (better) virtual comport splitter such as GPSGate. Anyway, trying to program the internal GPS via the GID port did not work at all. That's why I was next trying to get direct access to the hardware GPS port (COM3), which did not work either, before I bravely sent my device into boot loader mode (unfortunately with also no success)... Any other hints or suggestion are still highly appreciated. GeenZ

Serial Cable
Hi all, This forum being the greatest about HTC, I think you guys will have the answer : I would like to use my TyTN to connect to the console of a router (using serial connection) : 1. Does anyone know where I could find a miniUSB-DB9 adapter ? 2. Will there be a driver for serial port, or is it natively managed with COM ? Such cables exist but for PC, but not miniUSB and with a Windows driver, no info about the same thing for PocketPC. Anyone knows ? Thanks zEar - HTC TyTN
Re ---- DELETED Message where I thought I found it..
Understood the problem.. Hi all, AFAI understood I cannot find a solution due to the lack of USB Host support in the TyTN. I still wonder if the port can be used in direct low level serial mode as you see in bootloader. Could WinMobile use it ? Another way would be to have a device that would be usb host, putting the phone into slave mode, but maybe I dream... Thanks for any reply..
there is a bluetooth to serial adaptor which has been reported to work with the tytn.
COM1 Hi, After much googleing there's still hope. Windows Mobile presents a COM port : 'COM1 via cable' and in the specs of the TyTN there is RS232 communication. I still cannot figure out if the miniUSB connector pins could be simply mapped to the corresponding RS232 signals. Probably not Anyway I flashed the XDA-Live wm6 ROM and it's great ! the battery seem to last longer (still 70% after 2 days!) Thanks to the xda-dev community
TMC and/or MSND services for Trinity
Hi everyone. I have been doing an excessive reading looking for a way to have traffic info on Trinity, besides Google maps. Both iGO and TomTom provide TMC related navigation, and igo supports MSN direct as well. The problem is our Trinity lacks FM receiver for the service. TomTom offers TMC over GRPS services. It is offered only in Europe (I am in the US) and the service in California for TomTom is, how to say it, 'not accurate' . So I am with iGO8 and I am pretty happy with it. Now I am looking into a solution for TMC or MSND. Yes, I saw the GNS solution of adding a FM receiver and sending the signal over blue tooth, but it isn't going to work for me, as I can't add it between my radio and the antenna unless I pay some major $$$ to an Audi to do it (or lose warranty...). There will be an external unit in Q1/09 but what i am really into is to have the service emulated by code. Did any of you have found a TMC or MSND service through GPRS service? I am looking into a paid service (sure, free would be better) like MSND offers, but I have the hardware obstacle to pass... Ah, one more thing- never tried to connect a BT device to a COM port, and have hands free at the same time... I would like to find out if this is working or not, as I suspect the BT gateway on Trinity may have hard time with it while on call. Not that I care if TMC/MSND flow will stop while on a call if it resumes automatically after.. Thanks in advance.

Well, adding any hardware to an 'all in one' device is kind of defeating the purpose. I am specifically seeking a software solution, emulation, a signal over GPRS kind of solution. It seems there isn't one and I wonder why. After all, at least for MSND, it sounds kind of logical. BTW - XM radio has the MSND signal embedded, but again, no clue how to communicate it to the trinity... So adding hardware isn't a great one, but thanks of the offer. I have considered it before posting and turned it down. I'd like a phone in the pocket without running wires, battery operated devices, etc. I may be dreaming, but hey, even the new diamond , touch HD and fuze suffer the same problem, I think. I know the Diamond has FM radio, but still no TMC or MSND...
Hey Man , I've installed the GNS module in my Audi A3 realy easy so you should be able to do so. maybe explore that option some more. GreetZ
Which GNS module? The more I look for a solution, the more I am convinced a TMC over bluetooth is the solution... The only thing is I have no clue which is the right one to buy... Neo-morpheus, assuming we have the same connections needed, what was the one you have purchased from GNS?
Hi there, i have just purchased the GNS 5870 Bluetooth TMC, although its for my touch HD i will let you know the progress. BTW i never found any other way with any software to connect TMC through the radio, it just doesn't work at present. Some say it recognise's through IGO8 but does not connect Hope this helps
Argh ... looking for the GNS 5870 for a while ... could you tell me where you bought it ?
GNS trafficBox FM9 and trinity Hi folks, OK, listened to the advice on this thread, i have purchased a TMC reciever from GNS. I have a Trinity (WM6.1) phone and I use iGO8 R3. Setting up the TMC receiver in iGO returns only one thing- TMC hardware not found. There are 3 variables (can be auto or manually set): TMC protocol, COM port, and Baud rate. I am in the USA (California to be exact). Is there a way to make it work? Even if there isn't a TMC signal, why does the phone claims no hardware found? BigE
Well, I think that the first thing you have to do is to establish a "connection" between your PDA and your Bluetooth TMC receiver. From your PDA: - start/parameters - choose the connexion tab - start the bluetooth application - switch on your TMC receiver, - select "add a new machine" (don't known the exact wording, I've got WM 6.1 French version), - when recognized, select your TM receiver and then click next - enter the authentication code (if requested ... usually, it is as simple as 0000 ... should be part of your TMC receiver documentation), - after that, you should associate a port number to your bluetooth TMC receiver (don't remeber exactly how to do that but this should be done from this application ... anyway: google is your friend ) After that, start iGO8 and move to the TMC configuration page. If the automatic detection does not work then: - select GNS, - select the port number you have just chosen - select a bitrate (or keep "auto" ...) And that should work @+ JBM

Could you post any pictures, video or screen shots? Thanks
not sure that GNS 5870 is already available (mass production: Q1-2009). I used to use a Royaltek TMC+GPS receiver with IGO8-R1 but this one is now out of order now.
Gns bt gps+tmc datruth , Can't confirm, as I did not buy it. I don't see a reason to spend 120 Euro, plus shipping (another $25) . The trinity (and the Fuze) have built in GPS, and i hate carrying two devices instead of one. if I was going to have a GPS external, i wouldn't bother buying a device with GPS.. I tried having TMC only added. With the serial port solution i failes, as it sems most HTC devices do not host the serial port (hence both the GNS device and the phone are clients) . GNS tech support offered my to send it back. i did not make up my mind yet what I am going to do. In the meantime i am trying Zeno's serial port host driver as the trinity supposes to ahve the hardware for it, but it looks like client and host have different wiring to the USB connector, as it still does not work. GNS claims only BT is the solution. I was too busy to take it on, so in the meantime, all I can confirm is serial port will not work for most of us.
correction: GNS 5870 available since Feb 2009. Waiting for mine (delivery in progress).
Is TMC a free service in the US? I read on another site that even if I had a compatible TMC receiver for my HTC Advantage running iGo8 I would still need a subscription to get traffic updates. Is this true? Has anyone been able to get traffic working at all in the US. I was under the assumption that the TMC service was similer to GPS. It's broadcast everywhere and you just need a receiver to take advantage of the service. Am I wrong in my thinking? This is a reply I just received from the company GNS. thank you for your inquiry. Yes, the GNS GPS-RDS/TMC-Receiver 5870 (see: http://www.gns-gmbh.com/shop/xtc/pr...DS-TMC-Receiver-Bluetooth-32-channel-GPS.html ) works also with the navigation software iGO8 and HTC Advantage 7500. But you can use the GNS TrafficBoxPlus-FM9BT-Y (see: http://www.gns-gmbh.com/shop/xtc/index.php?language=en& ) as external Bluetooth TMC-receiver, which is less expencive then the GNS receiver 5870. PS: Please check if your navigation software (and maps) supports the american TMC service. Best regards Gerd Sept
How many BT can work simultaniously? I wonder if I am purchasing the BT device and pair it to my phone, can the HTC device handle both TMC signal and a BT headset at the same time? From GNS I was told the USB version I have will not work with Trinity because the USB is a client and not host on most phones. I tried installing Zeno's usb to serial and it does not work on my phone. I still can not identify TMC hardware. As for iGO and American TMC, I guess the folks writing iGO took care of it, as they support so many different protocols, there is no reason for them not to identify the American TMC. And if there is a paid service? Not that I know who offers it in the US. I assume it is off air and all it takes is a receiver, but since I did not have any success connecting, it is just a guess.
