Where is the GPS Antenna located on a 2015 XJL...I think that is my navigational problem....

 

It's in the shark fin above the rear window.

 

Can I get at the fin from inside the ceiling light???Does that come apart???? There may be a disconnect or???? or needs a new fin or ????

 

The headliner has to come down and it's bolted to the roof.
Looks like this when you get to the bolts;





But it's not a problem that's been reported and you should get it diagnosed before just replacing parts?
Have you run the codes using a SSD type scan tool?

Might be something simple and cheaper?
