have you tried starting the device emulator as a low priority task?
that's how I'm running it.
did u manage to connect up the GPS by the serial through function? I've got a BT GPS mouse that is connected to the carputer's COM3, and have mapped COM3 to the device emulator's COM1. Then told TomTom to use COM1 as the GPS but nothing happens. Did you get that far?
otherwise have a look
here for reviews. I was considering copilot since I heard it has a traffic function, but I've not found much info on that.
