Our government made an update to the GPS system which resulted in the wrong date being displayed by our older radios. I have no idea if anyone is working on a work around.
I dropped off my 2005 955 at Rusnak in Pasadena for the transmission recall and asked about the the issue with the wrong day being displayed. The service writer gave the appearance to having HEARD about it but Porsche has no solution yet or any in the works.

At that point I began to in a very detailed manor give an explanation as to what the problem was, “the issue affecting older 995s 996s 986s because of the 1024 week cycle of the GPS system, and the turn over from week 1024 to week one was the source of the problem. Some owners reporting discrepancies from one day to literally years.”

Her reply “Porsche doesn’t have a solution yet.” It was hysterical because the 2 customers in the chairs on either side of me slid their chairs back to hear my description of the problem. Perhaps they also had affected cars.

I checked if my Durametric was able to code the date ... nope. I’m going to send an email to Durametric tonight to see if they can add this to their product.

Has anyone done the old CONTROL-ALT-DELETE ? Disconnecting the battery? I don’t have the desire to take out the drivers seat quite yet.
