Hi
Ok you will most likely think I am stupid here. I upgraded my nav computer from (don’t know if its MKII or MK III) to a MKIV however i cant find the GPS antenna cable.
I know that one of the model had a GPS receiver separate from the computer and this must be what I had. The only 2 cables with the correct fitting that i can fine go into my TV BOX 1 is the TV antenna and i think the other must be the Phone antenna as if i plug it in to the computer it wont work (cant test the phone as the headset was missing when i got the car Doh).

So if nether of these wires or what I am looking for where can i find it and what will the box that it is plugged into look like?

Please help
