The navigation on my 997 C4S is apparently thinking I am some place where I am not. It seems to be about 30 miles off. Does anyone know what might be wrong? I recall this happening once before, but it corrected itself after a few rides. Not this time. I recently had my windshield replaced. Are there wires, sensors, etc. near the windshield which might have gotten disturbed? Is there a way to reset the navigation? Thanks, Al

 

Slow down and the sats will catch up with you.

 

If a reboot doesn't clear the problem take it back to the dealership. There is a known issue with the antennas in some units.

 

How close to D.C. are you?

 

I'm having the same issue with my Navigation after my windshield was replaced. How'd you end up fixing it?

 

swap it with an Lexus unit

 

I had the problem once but it fixed itself. It's been fine ever since.

 

Many times the windshield installer forgets to reconnect the electrical connector to the GPS antenna.

 

 

the GPS antenna is located on the passenger side trim cover, just below the front windshield. perhaps something is unpluged?
