i600 and TomTom GPS

[Guest Nikdc]

Hi, I have an i600 with WM6 and have installed tomtom v5. I have configured my 3rd party BT GPS in WM6 and select it as comm port 6. when I run TT5 and try to configure the BT GPS, it shows me 4 comm ports but I can not select any.

How do I select comm port 6 in TomTom?

Thanks,

Nik
