Dell Axim X51v HGP-100 Gps

Can someone please help me? I recently bought a Dell Axim X51/V HGP-100 Speaker Mount with Built in Gps for my Pocket Pc (Dell X51v). I am having trouble trying to set it up, I’m using TomTom Version 5. When I select NMEA GPS. I get four options to choose from, they are:
1) Native IR:
2) COM3:
3) BT UART on COM5
4) Se???a ?a??d?? st?? COM1
When I choose one of these options I get No GPS device on the TomTom. Can someone help?

The base port will be com 1. Select tht, then when you get booted back to the GPS signal screen you should see a black and yellow symbol on the right start to turn. If that's turning, then you simply need to get a GPS lock.

Confirmation of correct settings is the TT display showing "GPS position was lost....". IME connecting a GPS device then starting TT, TT will seek out all possible connections for a GPS device and connect automatically without user intervention (may take upto 2 minutes esp for BT devices). Well that's my experience anyway!
