I have a 2013 Fender edition Turbo Beetle Convertible. The CD player just stopped working. When I try to insert a CD, it pops it back out and gives me an error message---something about media not found. Any suggestions on troubleshooting or is this an issue requiring replacement? Thanks so much for any input. The car only has 40,000 miles on it so I'm hoping the CD player is not "done".
