Can someone with a factory navigation setup post pics of the wiring on the back of the navigation unit.

is X3 using the iBus Nav? the MK4? if it is so, then the GPS antenna should be inside the Nav computer, as it is built-in... older, MK1, and maybe even MK2, had external GPS antennae.
if it is a different typeof Nav, then - sorry, i have no idea... |

Ok it seems that there is a GPS antenna in the Shark Fin but it is used by the TCU bluetooth unit. On a OEM installation is the Antenna in the Shark Fin shared with the Navigation Computer? If so how?

I think the shark fin is only for phones. The x5 GPS antenna is under the rear spoiler. I don't know about the X3. Trace the small single wire from the right rear side of the MKIV. It is the GPS antenna wire and the antenna is like a little puck. The GPS receiver is a small card inside of the MKIV box.

Attached is a photo I found on the internet of the underside of the Shark Fin, from what I can tell my car has wires running from each of these connectors but without extensive removal of trim pieces I will not be able to trace them. Can you provide a photo of the rear of your MK4 with the GPS wire attached? |
