hi all, hoping i can get answers here, my Earthmate LT-20 mouse gps reciever is a pain, i installed the usb to serial emulator from delorme, when i open mapmonkey, it detects the gps reciever and you can see the tracker moving on the map, my problem is when i try to route my destination, it doesnt give me voice prompts (turn by turn direction) and it doesnt even recalculate route when you drove on a different street. anybody had the same problem? please help me, it might be a driver issue or something. any help is appreciated. thanks
