Purchased the car with navigation not working.

After disassembling the mirror, can see why the GPS was not seeing any satellites (and a xentry scan showed an open connection)



so the offender...notice the crack on the casing.


its location on the driver side mirror.



The telephone antenna must be removed to get the gps antenna. Once removed, one T10 screw is used to hold the antenna in place. After removal, a twist and the antenna comes out.

Now, i ended up removing the driver side mirror entirely so i could fish the gps antenna out.

I used a cable routing kit that i use for internal wires in bicycle to help so i can pull the new cable.

Here it is on the old cable



More than likely it can be done eithout, but i did it with made it easier.

here is the new gps antenna (red cable)



and the old vs new GPS Antenna



And the gps antenna installed.



Once all connected in the door.

Gps is operational with 12 satellites aquired.

Part numbers:
Old - A2139054401
new - A2139055009

Time taken... 2 hour-ish.
