...but what brought me here was how to get Information about a SD Card Navigation hack, is there any good posts around here? System Engineer since 20 years, so i like of doing things on my own when i can save a few bucks...:nerd:
The AIO and AS Built threads have tons of information on messing with the system. I haven't done any of that myself, as I'm too worried about bricking the system and having to take it to the dealer. It works for lots of people though.
