166 Navigation deck upgrade/reset?
I have a G3 navigation deck purchased new, which worked perfectly running a Porsche PCM CD. I was forced to do this because it is the only mapping that works for North America.
Then, I inserted a 2001 G3 German CD. The CD seems to have upgraded the firmware. Now, the PCM mapping does not work. There must be a way to reset the deck to the original firmware as shipped.
How to perform a reset on the G3 nav deck?
