Hi

So, if you follow my channel for like, an eternity... lol... you have seen this car... was a long time ago, but is now back with new problems, and also to finish what the owner decided not to have done at the time...
I am starting the video by explaining an issue that for some weird reason I decided not to record, that said, was an interesting problem that came with a lot of work!
After that, the issue with the audio system...
The car had no sound, no radio stations plus some other issues... all because of 1 module...
Follow me on this video to find out what was the problem and how to resolve it.

Link to the old video on this car, be kind, was recorded quite long time ago... :-) :
