Hi guys/girls,
I've just sold the original manufacturers double din head unit out of my 05 Impreza and the buyer has since fitted it and requires the code... Does anyone know where I would find this?
Sorry if its a dumb question!!..

I can't remember needing a code for the HU from my 05 wrx (this doesn't help you, of course).

Are they sure? I may've forgotten about it though...

Beev!!!

I'll ask him whether he's actually fitted it or whether he just presumes it needs one.....thanks alot!
