    But do the radio manufacturer say it also uses the CAN bus for diagnostics?

    Almost certainly not IMHO... the scans for every other car I have seen fitted with an aftermarket radio produces this error on 5F diagnostics even though all the other functions such as info and controls work.

    I still think asking the seller would be the easiest way to address the issue. You have a contract with them since you paid them for the unit on the basis that it should work with your car. Since it's not doing as you wish or expect, I seriously think that messing with your car blindly to try and make it work isn't a good idea. You could well end up with more wrong than you start with.

    Have they given details? An aftermarket device supporting factory diagnostics would be VERY unusual, so there's reason to doubt that...
