Hi all,

I've a bit of an odd issue where my car seems to have some point had an M-ASK head unit installed where from the factory it should have CCC.

The only issue I've found is the phone book doesn't seem to be able to connect (which is actually a bit of a problem for me), everything else seems to work ok except I get "head unit not coded correctly" then "head unit not programmed correctly" on startup.

As this isn't what is meant to be installed (and I've never coded anything in my life, though I'm sure I could learn) how would I correct this?

I'd install the correct CCC unit but it really doesn't seem worth what ebay sellers are asking for it, considering how old it is!
