Sorry mate, simple answer is no. It can be done but have heard it is quite tricky. Best bet, depending on your spec, would be to buy an aftermarket headunit.
PS, welcome to LOC
Thanks,
I think you are right, put off the idea of an s/h unit in case it happens again.
I've found mention of Removal Instructons in the "Workshop" area, I can't for the life of me find them, anyone got a Link/Copy?
