After I have started GPS Tuner I can not got signal from my GPS Receiver. Why?
At the first use you have to define the COM port and Baud Rate for the correct communication between GPS Receiver and your PDA. You can reach all the functions for GPS Receiver in GPS Settings panel.
When I launch GPS Tuner, I am asked to automatically configure GPS Settings. After a few seconds the screen freeze and I have to soft reset my Pcket PC
Seems that the .NET Compact Framework's serial port reader is not fully compatible with some integrated GPS device. There is a workaround for this problem. Please
download the free JAL Port Splitter application and install it to your PDA. Before starting GPS Tuner, please start Port Splitter and set your
input GPS port (write manually COM4 into the box) and an output virtual port (for example COM5). Then start GPS Tuner and
set your GPS port same as Port Splitter's virual port. Please do not let GPS Tuner to Auto-configure your GPS receiver, please answer 'No' for that question. If you can not start GPS Tuner (because of freezing), you should delete the GPSTuner.ini file from GPS Tuner's folder also.

I do not know my COM port and Baud Rate settings.
In this case select 'Auto' Setup option from Port box, and GPS Tuner will try to find your GPS Receiver and set the Port/Baud Rate automatically.

My GPS Settings are OK, but when I tap the Start button nothing has happened. My TomTom software works well. Where is the problem?
Other users reported that the TomTom software has locked their port (and GPS) so other applications could not work.
TomTom's GPS driver constantly holds open a connection to the Bluetooth stack on the Pocket PC which results in a failure with any other application wanting to talk to a Bluetooth GPS.
1.) Try to download the latest GPS Driver from TOMTOM
or
2.) Uninstall the GPS Driver manually
a.) Go into START | SETTINGS | REMOVE PROGRAMS
b.) You should see a program called "TomTom ~ GPS" (without quotes)
c.) Tap REMOVE and answer YES
d.) The new TomTom Wizard will appear asking you to reset the Pocket PC
Now you will have a fixed connection and you will be able to use other applications again with your Bluetooth GPS Receiver and not be confined to just TomTom Navigator 2.
