Sorry for long winded story.
Had a black screen of death and took it in to the local dealer. I told them to specifically test the APIM. When I picked it up they told me it was the FCIM(the trim panel with the fan and volume knobs) and it was $1400 to replace as well as the laundry list of other things they checked that need to be replace(oil change, windshield, tires,etc). Charged me with 1/2 hr labour. I knew it was wrong so took it to another dealer and they were familiar with the problem and also said it was a 2 hour procedure for diagnosis of the APIM. Anyway they came back with faulty APIM. When they replaced and I was checking it over in the lot, the nav was not there. So go back in and they look up the build, no nav listed. They then did a window sticker look up and it showed nav installed, so they took it back in and reprogrammed with nav licence. All is good so far.
The question I have is can the backup camera function be enabled just that easy as well? Would be nice to add without a lockpick.
