Hello everybody, I need some help identifying the connections for my sound system. I bought the 2004 Discovery a while ago and have only just got round to sorting out some music. The picture below shows what connections I have, however I have no idea what system used to be in the car as it was sold without one. I have a CD changer under the seat but I don't want to use that. I'm not too fussed about the steering wheel controls either. I would quite like to buy a head unit such as the Alpine CDE 170r, will this be compatible?

Many thanks in advance for your help and I hope you will forgive me for asking a question that's not about off roading - I do use this as my daily car as well!

Autoleads do an adaptor to allow you to keep your dash controls. You need the adaptor lead and a 2nd "patch" lead which is brand dependant, that connects to the radio.

Grey & orange connectors are speakers & poss dash control by look of it the yellow/green block seems to have power supply memory feed etc, Fook knows what the Blue connector does.

Head over to the Autoleads site, they have all the connector and pinout diagrams etc.

Hi, thanks for the reply. Autoleads' website has just made me even more confused. Apparently, I need a product code: PC9-4xx as I think I have the high specification setup. How do I know what the two Xs are?
Thanks

Think ya need this one???

Thanks redhand... I've decided I am just going to pop a Visteon 6500-CD in there. It has the same connection that I've got and I presume they're for the same thing. Land Rover Disco 2/Freelander Single CD Radio LR006192 | eBay

This way I can completely ditch the awful 6-CD Changer but keep the use of my steering wheel controls.

The grey plug is for power feed, steering wheel controls, telephone mute and illumination control.
The brown plug is for the speakers, fed to the amplifier under the passenger's seat.
The blue plug is for the CD autochanger under the driver's seat and feeds the audio into the head unit, along with the control signals (I-BUS) and power feed to the changer.
The green and yellow plugs seem to be to do with the headphones system and also an I-BUS control to the amplifier.

The larger of the two coaxial plugs is for the VHF radio aerial input and the smaller one is for the Long/Medium wave aerial. The "high-line" ICE system in the Disco uses two aerial amplifiers, one on each side with the aerials being etched on the window glass of the rear quarter windows.

I've put the full pin layout of each plug at:

Hi Brian, so does this mean that I won't be able to use the Visteon system. I've found out that the original system was the R990. However, I'd rather not have to use a tape player if i can avoid it.
Thanks for the clear info though.

I'm not advocating that you're stuck with the tape player, I don't use it.

As for replacing the head unit with an aftermarket unit, there are many members on here who have done it, usually with an adapter lead, although some have done it without and some have managed to use the amplifier and others have by-passed it altogether. I would suggest that you do a search.

The system I have is the factory fitted high-line R990 (not the Harman-Kardon) with a small FM modulator, not an FM transmitter to inject the audio from my mp3 player into the VHF aerial. This allows me to use any radio channels, my mp3 player, the CD player, even the tape player if really necessary, and I have the steering column controls too.

There are other methods of doing it which I'm sure somebody else will come up with, but my method suits me.

If you intend ditching the autochanger then I would hazard a guess that the I-BUS (visteon) system won't be required either.
