IPAQ 1940 + Tom Tom 5 COM Port Problem

[ukjag]

I'm in the process of trying to set up my IPAQ 1940 and GPS connection. The instructions say the GPS settings should be set to Baud Rate: 19200 and COM Port 1. I have an Arkon Powered GPS PDA Mount

I go into the software and select the following:

Show GPS Status-->

(Have to select one of the following:
Tom Tom Wireless GPS
Tom Tom Cable GPS
Other Bluetooth GPS
Other Cable NMEA GPS)

I select Other Cable NMEA GPS (I presume this is correct)
Select the Baud Rate of 19200

I then get a screen asking saying "GPS is connected to:
COM3
Bluetooth Serial Port...
Bluetooth Serial Port...
S2410 IRDA2410
S2410 COM0
Serial on USB

As you can see there isn't an option to select COM1. I have tried COM3 but doesn't work.

I have turned the Beam off under Settings-->Connections on the IPAQ. I have no idea how to check what COM Ports are being utilised on the IPAQ.

Anyone have any ideas how to get COM1 working?

I have proved that com port 1 works with active sync.

Many thanks,

Ian
