If anyone with a '15, that has NAV and a PDR, that has experienced problems with the GPS, you're not alone. It is a problem with interference between the PDR and GPS wiring that runs through the mirror assembly. GM is aware and developed a fix that is being performed at some dealers with success. Basically shielding the wires involved to eliminate interference.

I had the problem and it has been taken care of.

Glad they resolved yours doopoco. Would you be able to post the specifics of what was done to yours and also if you have the GM tec bulletin number that would be of great help. We will then post it over at http://www.stingrayforums.com/forum/stingray-corvette-tsb-recalls/ Thanks

They apparently split the wires that feeds the PDR and GPS and wrapped them with shielding to prevent interference. Took them about an hour and a half. My tech said that GM hadn't officially released a bulletin yet as he thought the lawyers were reviewing it first. That was as of last Wednesday.

Thanks doopoco for the additional details.

Bought my wife a 15 with PDR Nav. Same problem as everybody else. PDR wire is interferring with GPS signal. Way to Go, GM!
