Thread: Hp Ipaq with GPS hooking to a 7inch TouchScreen

Not gonna happen.
For one, there's no VGA out on the PDA. For two, there's no drivers for the touchscreen for the PDA (WinCE or whatever they're calling it this year).

However, should you put a full-on PC in the car, it's possible (no guarantee) that the IPaq w/ GPS could be used with PC-based Nav software.

Depends on a PDA. Some of them offer VGA out like hx4705 and Aixm x5* so you may need to pick those. There is no way to use USB touchscreen so you better pick serial one if you can find.
