Hi there, I have a RNS510 Nav Radio on a 2008 Mk5 GTI I purchased about 3 years ago.
For some reason now after about 5 minutes of working fine it seems to mute itself. The little 'crossed out speaker' icon displays in the top left.
When the radio is working normally and I press the phone button it mutes and the little icon shows up. When it's working and I press the phone button it unmutes... when it's not working nothing I can do will unmute it.
I've tried factory reset, I've tried taking it out and putting it back in, I've tried the <> & i* reset process... nothing seems to fix this issue.
Has anyone else had the same issue and successfully fixed it. The garage where I get it serviced said it might be easier to buy a new one.. so I did that, purchased a RCD510 via someone on ebay.. it plugs in but does not work.. so I want to try and fix this RNS510 if I can.... otherwise I have to then try to find another replacement, and that seems like a mind field with the potential battery drain issues.
I've search on various forums but not been able to find anything yet...
Hope someone has solved this before.
