Hi Anders, taking your notes I have modified the GPS POD and added three external contacts without wires to be able to use the Suunto interface cable. It works wonderfully.
Here's some pics of my modification...
1- This is the outside...I used the metal pin from DIL IC sockets.
The pin-out as seen in the pic are:
TX to POD, GND, RX from POD
2- Note the cut out needed (for connection pins) on the plastic part that holds the PCB in place
