On the subject of GPS configuration, I chose OTHER NMEA GPS from within the TOMTOM software which then brings up a Baud Rate Menu (I chose 4800) followed by a list of ports from which I chose GPS ON NAVMAN. Prior to running TOMTOM you need to ensure that the GPS device is turned on from within the settings menu of the PDA. Hope this helps. I`m going from memory so some of the descriptions might not be 100%.
