Hi, I just got me a 3517, with tomtom 5 and a BT-308 gps unit. I have paired the two units, and installed the software. The Ipaq can see the GPS and the GPS blinks at the corresponding rate for a connection. However, tomtom 5 cant see the GPS unit even when I configure the gps in tthe tom tom menu. I'm a bit of a newb to satnav software, is there something I've missed?
