I have a Camaro 2015 SS my battery died and I replaced it now the screen says its locked but rearview camera works fine. Took it to a dealership to get the codes they charged me $75 for diagnostics and they said I had to replace the Radio which costs $2500. Ive called two other dealerships and they told me I have to take it but I dont want to loose my time if they say the same thing it is really dissapointing that Chevy would do simething like that. What else can I do? I dont want to pay $2575 to get a new radio I spoken to several other mechanics and they say that is bs what the dealers are doing.
