I have a HTC touch cruise 2 which came with Tom tom navigator 7 pre installed. You need to activate TomTom to set it up.
If you go to HTC web site and download the manual for your device it will give you the full instructions on how to get your Tom Tom up and working
Hope this helps
I have a HTC TYTN II and TomTom finds the internal GPS fine.
In TomTom on the main nav screen, touch the status bar (speed, ETA etc) on the bottom right of the screen, then touch the battery/signal strength section on the right hand side of the screen, and lastly then hit the "Configure" button down on the bottom left.
You should be able to select "Built-in GPS receiver" (In Navigator 7). From memory in Navigator 6 or below, you just select Bluetooth and the Com port set up as your GPS hardware port (which you set up in Windows Mobile GPS Settings).
I have a TyTN II and I was able to get TomTom 6 to work great. The Following is a step by step guide to configuring TomTom 6 to use the internal GPS receiver in a HTC TyTN II.
1. When at TomTom main navigation screen, touch the Status Bar in the lower right corner, it contains signal strength and assorted stats you can change in Preferences menu
2. Next touch the Trip Info button that runs along the right side of the screen, it shows the battery meter, signal strength, and longitude & Latitude
3. Once your at the GPS Status screen touch the Configure button in the lower left corner
4. Now cycle through receiver choices until you come to Other Bluetooth GPS receiver then touch Select button in the lower right corner
5. Once at the Bluetooth warning screen touch Continue to move to the last step
6. Finally choose COM4 as your GPS receiver's port, you should now return to the GPS status screen.
NOTE: The first time you connect the the GPS satellite(s) it can take up to 5 minutes to connect. The more often you connect the faster it will be. Also I would recommended running QuickGPS to help speed up connection time.
