Hello I unplugged my Audi Concert 2 from my car an left it out of the car unplugged for some time (more than a month). Than when I plugged it again and I had red screen (seems like the back light of the screen ) I took it off again. I opened it and dried with an hair drier. Then I plugged it back again, it started to work for some minutes and then nothing . Does someone know how to fix these tipe of problem?
if its had water in it or you think it has I would just replace it, its a pain to get rid of the moisture completely and may have caused irreparable damage, if its for the A3 loads of people swapped them out for aftermarket stereos and the concert radio isn’t the top end one out of the S3 so should be relatively cheap to find second hand on ebay or other places in the web.
