COM Port set up for GPS adaptors

[Guest paulwest]

I have several options on the port configuration!!!

GPS settings as reached from the GPS icon on the settings page says "

Choose a port that programs will use to obtain GPS data...

Then I've got the option to select which port the GPS device is connected to

and the baud rate...

Then I've the other route which is from the settings/connections/bluetooth

route which shows the supposed pairings and allows me to edit the COM ports

each one uses.. I've got BT321, incoming and New outgoing as options...

TOM TOM says it's using BT on COM6 - so help - which is to be connected to which?
