Bluetooth GPS

hey can anyone recomend a cheap GPS bluetooth unit for use with a Magician and Tomtom.
cheap and nasty will do,

Look on ebay, there are loads to choose from

Yes check eBay but try to get the TomTom one as it works out of the box. TomTom can be a real pain to get working with other receivers.

ta yeah i was watchin a few on ebay,
was hopefull someone might have suggested a place to get them from cheap or something lmao

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=230047740000
ive just got one of these. if you get one go to the web site on the instructions. there is a little gps test program which when you run will find which com port the gps is on (close the prog fully).
When i tried to get it to work on tomtom i couldnt. so after a search on the tomtom site they say to set tomtom gps settings as 'another nmea wired gps with 4800 speed' use the com port found in the test prog for the gps
Works fine so far. only had it 5 days.

thanks yeah i got one last nite, similar to that (16 channels and such)
yep already seen some threads about special patches and stuff.
cant wait to try the Yoda voice that i picked up for tom tom.
"Turn left you must"

i just bought the qstars btq815 from ebay32 channel with solar panel.....got tom tom 6 on the spvm3100, only had phone a week so am real novice but i managed to get it up and running fairly easily only made a short journey to test but all seemed ok

32 Channel? Why?
There's only 24 GPS Satellites and only 12 can be visible at any one time.
Do you know if the receiver will also work with Gallileo when that comes on line? Then 32 channels might make sense....

need bluetooth GPS reciever
can anyone help to find a bluetooth gps reciever that works with XDA ATOM
thank you

well ive been playing with the qstarz bt-q800 for 3 days solid... gps on the window ledge in the house, xda 2i has run flat so many times that it on the psu now im still waiting for the gps to go flat... im really impressed with the battery usage on the gps.
I took the pair of them out for a walk round town yesterday. had tomtom running, walked down to the bus, go on into town. realised i was killing the battery on the xda so left tomtom running, turned the xda off with the pwr button on top. the gps went into standby mode. 30mins later turned on the xda, tomtom reported no gps, the gps then woke up within 20 seconds, and with in a further 40seconds had found my new location. quite impressed.
the bt-q800 also has an external aerial connector too. might think about getting one to fit on the landrover. GPS always has a bit of a problem in it because the front window is almost vertical so the roof covers the dash.

yeah tomtom standards are about 20, i got a 16.
even the navman will only have 3 active at any one time.

well i finaly got the qstarz to go flat... it was connected and tracking for 18hrs solid on top of being switched on for 4 days and doing several hours a day of tracking in that time,
. Im impressed just at the battery..

Only 3? - that's not good for accuracy and calculating your heading etc - you should connect to 4 at least to get the best accuracy.

yay 2 more days and i git it,
got the phone ready to go,
TOMTOM with aussie maps
including all POI's (speed cameras etc)

GPS psoition not exactly 25 to 50m difference

Hello,
my gps has no right position i think the difference is between 25 to 50 m
Is there a tool to correct this issue ?
Thx
Nochmal in deutsch falls mein Englisch nicht so gut zu verstehen ist
Mein GPS im Artemis hinkt etwa 25 bis 50 m hinterher was sehr nervig ist
Kennt jemand dieses Problem und weiß wie man Abhilfe schafft ?

From what I recall no civilian GPS is precisely correct.
Only Military GPS is precise to the metre.
Not sure what the exact varience is though.
Regards

i have navigation systems before the p3300 and on all when the street cross comes it brings exactly the position when it says turn left at 50m then it was correct, i believe the military difference is only 1m or lower not 50m ???
For external PC gps receiver there is a software for correct some options for the inbuild gps.
I have no glue for a in built gps.
Sorry for the English this not my normal language, i hope you can understand what i mean thanks

Also, better accuracy depends on the number of satellite signals the device can get. Signal strength is weaker in the urban areas.

What software application are you using when you notice the discrepancy? I have found my Artemis GPS position to be equal to some of my other units. For example using a topographical map when out walking the unit is very good, certainly not 25 to 50 M out. It could be low signal strength and reflections off other building that is causing a problem (if in built up area)
One other consideration, how many other applications do you have running at the same time as your Nav software, your device might be struggling under load, check settings/ system tab Memory icon/ running programs and stop all before trying the nav software Mike

My device, which is still the Magician is running the ROM 1.13 with BS. Additional software which are all installed in the Storage are; Pocket Informant, Photo Contacts Pro, Resco Suit, SK Tools, TT6, WorldMate Pro, Ring tones. All TT maps (WEU, USA+Canada), voices, schemes, zip codes, POIs and IE Temporaty files are installed in a 2GB SD. What's left in available memory are Storage = 0.7 of 26.72 MB, Storage Card = 105 MB of 1935GB.
The programs that are running (being memory resident) while TT6 is active are Photo Contacts Pro and Pocket Informant. I have BT on all the time since I use a BT headset for calls while driving. TT audio is via my Seidio active car holder.

The programm ist TT6 and only jetware, and ilauncher active nothing more, the area is no big city good sight to the air.
I checkt this with tt5 and a hp2210 with bluetooth sirfIII this combination is near perfect

I've never used those programs. The inaccuracy might come from any of the two.

Civilian GPS is officially (from the provider of the GPS System - US Forces) something about 10 metres unexact. Of course this number can be smaller if you have more satelites "in sight" However, GPS Navigation Programs do not need accurate positions, they calculate the position on the map with old data and then extrapolate it, showing the dot where you should be now, according to your speed and heading 1 second or two seconds ago. Of course it can control its calculation because more data streams in. It is funny to see Navigationsoftware Confused, when you ride a train. It gets a signal in a certain direction, with a certain speed, so it puts the dot on the street next to the Rails, because this is the only logical position where your car can be so it says "turn left now" but the train goes straight. Then it searches another street you could be on. just funny
But in short: GPS Software compensates missing GPS accuracy, mostly well, sometimes not so good. Try using another Software or newer map ,maybe that will fix the problem. On my MDA Compact III The Built in Receiver works just great together with TT6. Maybe there is a way to shorten the interval between two data sets. That would give the Software more information, resulting in a more accurate position. But i don't know if a program like GPS Maus can manipulate Built-In receivers that easy.
I once reprogrammed a T-Mobile Receiver with this program, so it received also NMEA data and the intervall between two data sets could be set randomly.

In the UK, the BBC send out a spoiling signal which reduces the accuracy of the GPS. It is also sent out from National stations in other Countries. I heard it was sent out with the atomic clock signal. This is to stop "undesirables" buying civilian GPS units and fitting them to military equipment and sending something directly to your letterbox - the same way a US military GPS unit can if they want to! You used to be able to buy a box that would correct the error signal, but that got stopped ages ago.
The GPS also becomes slightly more inaccurate depending on the speed you are travelling, travel under 30 mph / 50 kph and the "you have arrived" will be within a few yards/metres of the real arrival point. Travel at 70 mph / 120 kph and the "take the exit in 200 metres" is very inaccurate - maybe by a couple of hundred metres - you can work out why!
Also GPS signals are "secondary" and can be turned off at any time in the event of a military requirement - which is why you can use the signals free of charge.

Are you confusing the selective availability that was used to degrade the GPS accuracy up to a few years ago? - The US reserve the right to switch it back on again should they need to, but under normal conditions the signal is not de-graded any longer. If you want to send something to a letterbox the Post Office offer quite a good service

The issue of position inaccuracy relative to speed won't give a major difference to position - the software maybe responsible for the apparent degradation though.

As I mentioned before the US reserve the right to turn on the Selective availability (positional accuracy degradation), if they turn it off their own planes and other civ/ mil products would be useless - Mike

Static Navigation in Artemis
In Artemis is a Sirf-III-Chipset. One of the "features" of this chipset is a Parameter called "Static navigation".
This gives a more or less "static" position if the device is moving rather slow, like a pedestrian does.
Useful for car navigation because your car is not "dancing in front of the traffic light".
But it gives a more or less not accurate position when standing or moving rather slow. You need to move with 5 Km/h at least.
No tool for switching off "Static Navigation" in Artemis seems to be working.

BBC jamming the gps signal..?
Selective Availability:
"SA works, for the most part, by intentionally dithering the clocks in the 24 satellites that make up the GPS system. The clocks are steered by an algorithm, known to the control station and military receivers and transmitted in encrypted code over the satellite signals."
http://www.exn.ca/FlightDeck/News/story.cfm?ID=20000502-53

The BBC does what??? I don't believe that for a moment!
The GPS signal I get on my Orbit and previously on my Fortuna Clipon has been extremely accurate, using different software Tomtom 5 & 6, pocket streets and Vito all have been down to a couple of meters at most.
I have also used in the US, Cyprus and Spain all with the same accurate results.
Yes the US can turn off civilian GPS if they wish, which is why the EU is building Galileo.

duh... SA has been switch off 7 years ago!
interesting to see people still talking about SA, it has been switch off since year 2000!

Quick review of Holux 1000 gps...

Took the dive for a bluetooth gps this week...
Picked up a Holux 1000 from eBay for $24.99 Shipping was $19.99 priority.
Ordered on Aug-7, arrived Aug-10. from ebayseller gpsevyone.
Turned it on. Did a bluetooth discovery on my Wizard w/ WM5. Set it up on com6.
Live Search worked great. Google maps worked great.
BeelineGPS is a really cool tool.
The Holux 1000 seems to be so sensitive it picks up 8-10 sats sitting in my home plugged into a charger. Dont know about battery life yet. Its getting its first overnight charge.
Had it in my pocket walking around inside local market and could see location on my Wizard as I walked.
Anyway, thats my .02$ if anyone is interested.

Holux 1000
Hey,
I got the same unit and I can't believe how sensitive it is. Inside my house 18 feet from the nearest window (which had the metal blinds closed tight) it was locked in a few seconds and was picking up 8 sats. I had expected to need to keep this on the dash of my truck but there is no need I get great signals even with it locked in my console.
I use it with iGO mapping and it is Great! I'll never get lost again.
I'm gonna look into other software to use the GPS for, I'll try the ones you mentioned.
I got mine from buygpsnow.com.
Joe

Holux 1000 sensitivity...
Its very impressive for $25.
My Garmin eTrex Vista could never do that and you are right the warm up time is very quick. Its going to be interesting to see how long the battery lasts.

My P3300 Rocks for Golf GPS. Awesome!

Just for the guys and gals that love golf. I moved from my old Audiovox PPC6601 pocket pc (with a separate BT GPS dongle) to this device.
But, after first plugging it into the USB sync it died on me only for the mainboard to be replaced.
That's not such a bad thing since now it is stable as rocks and my IntelliGolf GPS application worked flawlessly. QuickGPS helps a lot to sync and at one point I remember taking my eyes off the golf ball and seeing 10 satellites synced.
That means, a much more accurate reading and if I haven't already mentioned it the fix on the course is very fast.
But, here's why this device really rocks for Golf. The extended battery I ordered from Hong Kong (2 just as a back up) can easily handle 1 round of 18 hole golf and it only used up less than half the battery!!! That suggests the device could handle 2 rounds of 18 hole golf (for 3 players).
Show me any other device that has integrated SIRF GPS that can do that and I will be impressed.
Happy Golfing.

its nice to see someone having so much fun with there device, and it bein very usefull too.

And what about the accuracy? There is famous static navigation thing, and maybe driving a cart with my XDA would be cool, but for walking i have such a mess in readings that it's almost unusable...
Cheers!

Good GPS-BT for Hermes WM6.1?

I was wondering if anyone knew a good GPS-BT thingy for the Hermes, one which has good battery and is somewhat portible to carry around..and connects nicely with say CRCs stable ROMs..
Any experience, tips&tricks out there? found nothing in the hermes forum for WM6.1..

I'm not running WM6.1, but I am running WM6 (K's rom). And I am using a G-sat BT-359. I'm assuming to would pair just the same, and work with google maps or MS live search just like it does on WM6.
It is small and stylish, fits nicely in a pocket. It makes it through a day of work for me, no problems (they claim it will get 11 hours on a charge, and it seems it will, but I haven't tried it on a long trip yet). It also paired nicely with my laptop and Street Atlas '05 played quite nice with it.
And the sensitivity is nice, much better than my old usb gps from my laptop, the BT-359 will receive satellites while inside my house, and have my location correct. It also works while in a pocket.
Hope this helps!

I just picked up the Garmin 10x. It was 120 bucks, but came with the map software for both my phone and my laptop. Works great, pairs easy. I'm using Pays v3(6.1) and no problems. The reciever gets about 22 hours on a charge.

I use the Garmin GPS 10x. It's small, rechargeable using the same cable / plug as the Hermes, has excellent battery life, and great satellite reception. I've had it for a little over a year and used it with Google Maps, MS Live, Garmin map software for Windows Mobile, and iNav software. Works well with any of them.

ebay
I got a gtop gps off of ebay 6 months ago for less than 40.00 and i am very happy with it. I have never run out of the battery on the gps. Navizon has paid it off and then some.

I have used a Deluo GPS unit that I picked up for $80 (USD).
It's nice that it uses a Nokia BLS-5 battery, so I don't have to rip the unit apart when the battery craps out.

GlobalSat BT-359
gets a fix in 20 seconds, SirfSTAR III chipset, replacable battery, $60
cant go wrong with this one, it got 5/5 in most reviews

I'm using the GlobalSAT BT-338
About 17 hours runtime on a full battery. Great signal recieving.
You can't go wrong with this one.

I've bought my second GPS receiver for it's size:
www.keychaingps.com
Link is for info only not price- I forget where I bought mine from but was £37 (GBP) inc delivery. Cold sat fix is excellent; always get a good signal. And best of all, put it on your keyring so it's always with you!
I'm using it with TomTom 6 on Hermes Schaps ROM and works great.

thanks for the many options, the hermes seems to work good with an external GPS-module, it's safe to buy one
I might get the keychain one, I only hope that it has a long standby time, I'm sure to forget to charge it and then suddenly need it..

My one seems to last weeks on standby- i tend to just 'top-up' the charge every now again just to make sure.

I also just bought the keychain, very good reception in Japan which is known to be a difficult area for gps, very fast, very small, and use time is 9 hour, very good time if you compare with the size.
Bought on ebay for 35£ + 10£ shipping. Best price possible.
And it's not sirf chipset but mtk 51 channels, compatible with 5 Hz information refreshing rate (still to be implemented in softwares...).
Nothing more to say... Enjoy!
(and perfect compatibility with Hermes+Schaps)

keychain seems the way to go for me too
so does it work when walking around with the chain in your pocket or rucksack? when you go tracking for example, or strawling through city streets..I've heard from a friend that his Orbit 2 (touch-cruise) GPS-function is useless for walking around..

I keep it in my pocket or in the backpack, so the bluetooth has a very good range I think. The only thing I noticed was that it needs to be in a very well-spaced area (sorry I don't know how to say it better, I mean you need to see the sky...) to get the primary signal, so I keep it in my hand during the 20 first seconds of switch on. But I think it's the same for every gps receiver.
Besides this, it this perfect. By the way I use it with Garmin Mobile XT.
Toni

Yep, agree with tonidekohlanta, you need to have it out for the initial signal then it can indeed be in your pocket or where ever (within reason of course!) and the signal is still strong.

Auto Powering on GPS
I do like the idea of a keychain for general usage but I would love that I could wire one into my car and as soon as it gets power it would switch on. I have BT3341 which is awesome but I cant mount it on my parcel shelf or anything as I have to switch it on whenever I want to use it. Anyone know of one that will power up as soon as it gets power?

aren't there devices which stay on standby bluetooth-on until the battery drains out? if so, just connect it to your cig-lighter in your car and let it run, forever!

The keychain as a energy save system : it goes on stand by when there is no bluetooth signal (generally when you close the gps software on your device). I didn't really tested the battery life in this case but one time I forgot to switch it off, anf when I realized it three days after, it was still working (but not for long maybe...). Also I heard that when the battery is low, the reception gets weaker.
By the way, keychain is delivered with cig lighter adapter (and the seller on ebay added a normal adapter which works also to charge the phone - very convenient!).
And also I heard somewhere that the holux gps receptor was nice, but I choose the keychain so I cannot say more.

I bought Holux M1200 for me and my wife. Works perfectly with TyTN and Touch. I keep it attached to the sun visor and it has great reception.

you can run into ports detection problems (in software like iGo) in some roms with htc home plugin. But it works fine if U reset software and turn off htc home from todays screen.
