Hi all, can anyone advise me: I have a friend who has just bought a '99 Vauxhall Vectra with a standard Vauxhall Radio Cassette in it with the display mounted remotely from the head unit. He wishes to install a CD head unit, or multi changer. Does he need a VAUXHALL part, or is there anything else that 'may' fit, and utilise the remote mounted display, i.e.. a multi changer that would be compatible with the standard head unit? The fitted unit has the following markings 400/4664 and also GM400V1638220. Many thanks for anticipated help and assistance with this, Dave Ridout
