Hi folks, close anyone know which of the connectors at the back of the Amundsen II do what? I know the yellow R pin unit is for the remote usb, but what are the three antenna connections? I suspect one is for the satnav, and maybe one for the dab, the third for the normal radio but which is which and does the unit have the dab antenna built in? Reason I am asking, my unit has gone and I am fitting an after market unit and I would prefer to use the built in antenna instead of adding more. Any help would be appreciated.

One of the DAB antennas is the heated rear window.

Thank you
