CD Changer

I bought a used CD changer for my RT3 system, it is the correct unit but I can't find the connections for it anywhere. I know they are fitted between the front seats on the UK version, but I still can't find any trace of the power & interface cable. I checked under the carpets, under the dashboard etc.

I know the dealer will have to activate it, but I wanted to get it all fitted and then ask them to activate the CD changer at the next service.

Has anybody got one and if so can they see where the cables come from.

Thanks

Mine is covered in matching carpet. I pulled that off and found a multi-pin connector at the back of the unit. The cables from that are routed underneath, come out from under the front, then disappear under the carpet again at the front right hand passenger seat fixing. Presumably from there they go under the carpet and up to the RT3 unit. I don't know if the cable would be pre-installed though, I'd have thought it only got fitted with the multichanger in the factory.
