I have the Alpine CVA-1004/1003 system with a matching DVD player dash mounted in the coach. The Alpine CD changer quit with an Error Code 1, which apparently means SOL in Alpine speak since it requires a head replacement or repair. Not happening on a 10 year old unit. So I’m looking to replace the changer at least. What brand or type of clean modern radio do y’all prefer to replace the original in dash system?
