Wired GPS receiver.....can it work?? - JAM, MDA Compact, S100 General

The topic titels says enough. I have got a cheap SMB connector wired GPS antenna, I can plug it in the PDA, but my GPS program can not find any GPS signal. Are there any settings I need to change or is this simply a mission impossible to make it work?

why does it take so long to get gps-signal?

hey guys,
i have a little question,
i just bought a haicom gps receiver and use tomtom 2 software. When i get out of my garage, it takes always more than 15 minutes to get a signal. sometimes during driving i also lose it. How comes?
when i connect my device to the receiver and power, i get something like "connecting to t-mobile MMS"...
oh, btw i have a MDA II with latest NL t-mobile rom. 1.60....
if anyone could help please...
thanks!
The gps should only take this long when first used, after that it should lock in a matter of a couple of minutes, to test the gps properly it is best to test it outside the vehicle, I think most Haicom mouse gps come with magnetic base so stick it on the roof and drive around, if it works better it is probably becuase your car has a metallised windscreen which blocks the signal. The message about connecting to the service provider is an error due to the com port being accessed i think, mine used to bring up activesync every time but once I canged my activesync settings on the xda to manual instead of auto sync it solved the problem.
so i should always drive around with my window open?? and stick the receiver outside the car?
I would agree with Crusin Through - I think your car may well have some form of heated windscreen or heat reflecting windscreen. What car do you have.
If when you do place the receiver on the outside of the car you do get good signal you can get a special anntenna that had an outside part and an internal part that you can fit permanently to the car so you can still move the thing about. Bit like a mobile phone antenna.
Alternatively as you have the XDA II you can get a bluetooth receiver an place it on the rear parcel shelf (I think the wider heating strips won't affect it - but can't confirm it.)
John, I wasnt suggesting you drive around with your window open, I was suggesting a way to ascertain if your windscreen is the problem regarding your blocked gps signal, by the way I have used a gps on the roof and the window will shut almost all the way however as the last post mentioned you can obtain a re-radiating antenna, this will solve your problem if indeed the windscreen is the culprit.
Re-rediating antenna - that's the word I couldn't remember :lol:
ok guys, thanks. i'll try with such an extern antenna.
thanks for your help
Before you spend your money on the re-rad antenna - try the thing on the roof - if this works then the antenna is your only real option if you want to continue with the thing in the front windscreen.
I'd hate you to buy the re-rad and then find it doesn't work.
Incidently what car do you have? (Does it have a heat reflecting or headted windscreen)
And if it works outside,
you still don't have to buy an external antenna, as normally the windshield have an area where is not metal coating...
try to check the manual of your car..
i own a toyota Camry 2002 model, it has indeed a windscreen etc...

diagnostics for bottom connector

My gps system stopped working today. Is there any way of diagnosing to see if its the connector on the phone thats gone tits-up?
I don't know anyone else with an XDA2 you see...
When you say it has stopped working, do you mean no signal, gps not found error or light not illuminating?
I run Tom Tom with a cabled GPS receiver which doubles as a charging cable.
I still get the green charging light, but no GPS signal.
It was working fine. Go into a service station for a bite to eat, and unplugged the receiver. Come back after being fed and watered plug it in again - nothing... No settings have changed, which makes me think its something to do with the connector - either the XDA or the gps receiver.
...but how do I rule out one or the other?

Gps Antenna Is On Sale At Cnn.com!!

what is this about, if gps is not working, why do they sell it::
http://cnn.cn/shop/8525tytnhermes-antenna-p-1615.html
ya, this doesn't make much sense.
Looks to me like a TYPO that should read GPRS or external antenna for car with the connector on the cable. BUT it would get a few buying it first and finding the mistake afterwards wouldn't it!
Yeah, it won't work although it is a GPS booster. I use the same make with my tomtom. It would only help plugging it into a GPS receiver that in turn is connected to the TyTn by cable or bluetooth - not as they show it directly to the Hermes.

External gps or miniusb adapter ?

I just got my hands on a rds / tmc reciever from tomtom. It has a connector which is on the tomtom go's. I was wondering if it is possible to connect this to my kaiser by an adapter. I also was wondering if anyone could tell me what type of connector the external gps port is and what type of port is on the go? Perhaps I can make my own adapter but I need to know what type of port it is.
Kaiser already have the built in GPS?
Why you want to built the adaptor for??
I do not understand what you asking here....
It's a TMC rds reciever from tomtom. It will update any traffic jams and mobile speedcams. It would be great if I get it working on the kaiser. It seems that the coax connector in the kaiser is a MS-147-C(LP)-2 connector. The tomtom tmc module has some sort of a 2,5 mm jack connector but with a metal ring around it. I can't find the name of the connector anywhere. But I'm sure if I can find out the names it would be possible with navigon to update traffic on route.
yes, i'd also like to know what kind of connector is on the AT&T Tilt/kaiser. i bought an external gps antenna for better signal, and thoght id figured out that it uses the MMCX style connection, but after receiving it from Ebay, it does not fit. Now i ned to find an adaptor to got from MMCX to Tilt GPS external connector, or splice a new correct end onto my external antenna.

The port on the Kaiser is only a connection for an external GPS antenna. The Tomtom RDS device uses a proprietary data interface that doesn't carry the same kind of signals at all. You won't be able to connect it to the Kaiser.
I found the MS-147 connector at HighRose corp, but they want $25.00 US for that tiny little connector. I only paid $12.00 for my ext gps antenna. So, I'm trying to go the sample route for a free connector. Said they were gonna ship it this March. Long time to wait for it, but better than paying that crazy amout for such a tiny connector. I could machine a one'sy order like that on the lathe at work for way less $$$ than that. And they are prolly running them on a CNC Screw Machine, pumping out 1 part every 3 to 10 seconds. Uggghhh.
Shaggy
This just isn't going to work, stop trying and either give the RDS/TMC receiver to someone who has a compatible TomTom or put it on eBay. believe me this won't work....
Just buy Garmin Mobile XT for your Tilt. It has traffic updates.

HTC X7500 - can't connect to two GPS antenna for topographic relief

Hello, my name is Manolo and i'm a surveyor. I'm trying to use my HTC X7500 as a data controller for topographic relief. I own two Topcon hiper pro gps antennas than can communicate with a controller via bluetooth or RS232 cable.
My problem is that when i connect via bluetooth the athena x7500 to the gps antennas, it can see both of them, but it can't hold always the to connections separate at the same time. 99,9% of times i belive the athena connected first to one gps antenna and second to the other one, but at the end i understand it gets the signal only from one. So, to bypass the problem i tryied to connect the athena to one gps via rs232+usb adapter and the other one via bluetooth, but i can't get the rs232 connection. It seems that only Hp ipaq hx series can handle the rs232 connections.
Any suggestions?
Any software that manage bluetooth connections?

Thanks,

I don't know if this is relevent, but here is a hint...
When I used to have a bluetooth gps antenna, I had to set up an outgoing com port dedicated to this antenna.
Have you created two different outgoing ports in the bluetooth options, one for each antenna ?
The guy on this thread - http://forum.xda-developers.com/showthread.php?t=515103 - found a usb-to-serial solution for his problem. Maybe he could help you. He also mentions some sort of hardware/driver he's used.
Hope this helps.
Thank you MysterD for answering.
Yes, i tryed to give a different COM to gps antennas, but with no success.
For working with this GPS antennas Topcon gives you also a PPC/Controller (named FC 100), with the antennas. So, HTC 7500 should be an emergency controller that i bought when the original controller got broken and i sent it to the assistance.
So, i checked the Software settings on the original Controller, and it connects on the antennas via bluetooth always on COM8. Yes, same port for both the antennas!
Infact, when i start the software:
1) it scans for bluetooth devices
2) i select the first antenna (a base antenna that i live in a point and don't move it)
3) it disconnect from the first antenna
4) it scans again for bluetooth devices
5) i select the second antenna (rover antenna, that i bring with me during the mesuraments)
6) the software goes into a mesurament menu and o start working.
On the HTC i must search the devices first and than start the software. That's the problem! If i give the same COM8 at both bluetooth devices at the same time, HTC gets confused.
Thank you Wovens.
I'm gonna try the drivers. Let's see if they work!
And there's no place in your software that would enable setting that first antenna should use port COMX and the second one COMY ?
Also, have you tried disabling the feature that lets Windows Mobile manage the GPS ?
On my Diamond, i go to Start > Settings > System > External GPS ("GPS Externe" on my French rom) > Access tab ("Accès", the third tab...) > Uncheck the only option on the tab (manage GPS automatically "Gérer GPS automatiquement" ...).
Yep, i think i already tried, but i'll try again and let you know it tomorrow.
Thanks
Okay,
assigning different ports to bluetooth devices seems working. But there is always something wrong: i can't start mesuring when i get into the mesure page. i don't know, i'll try to figure it out. Thanks anyway.
To connect the cable to the athena i probably need a driver for windows mobile. I'll try to find it.
Thank you very much guys,
Manolo
You're welcome.
Let us know if you succeed in getting your measures done !
