Hi all, new to site as I have just bought my first range rover.Can anyone tell me if the wiring fr cd auto changer is already in place in boot as standard, if so how can I identify it?. Any tips greatly appreciated.

No. If you have the low end hi-fi unit without CD controls then you will have to change that, then add door amplifiers and all the extra cabling too.

Having said all that, if you have a 2001 you have an Alpine head unit? What I said above applies to the <99 Clarion units.
