I am also sorry to report that we do not have a wiring harness to integrate you Sony to Land Rover's wiring. Your Land Rover has 2 factory amplifiers, one driving the subs and the other for the rest of the speakers. The amplifiers do accept a speaker level input but, due to the unique nature of the plug configurations you would need to cut off the factory speaker connector and hard wire the speaker outputs of the new radio to the inputs of the factory amps. I wish I had easier solutions for you.

above is an answer i got from Crutchfield. has anyone put an aftermarket head unit into there Disco without re wiring the whole system? is there a FAQ on this topic?

Don,

I think it would be wiser to rewire a new head unit when you put it in. The factory unit only has high-level outputs so you need to put in high-low converters to drive any extra amps you want to add on, which degrades the quality of the sound.

If you buy the unit from the Good Guys or Circuit City, they usually charge
about $50 for installation, plus cost of wiring.
