Thread: Factory Nav Screen install?

Has anybody here removed the standard radio/cd & installed a Factory 7" screen & all the other
( GPS CD RADIO ) components into a L322 RR.
Im trying to find out what is needed to do the whole job.

There is a youtube video online available but im trying to find a after market set up as the factory one seems around 3k complete set up there is a lot involved and then who knows if the factory wiring loom has all the plugs laying dormant?
Online ebayuk seems to have alot of stuff ie screens, (factory) 300 Pounds so for a screen its ok but then the rest of system is still needed.???
