YES! Absolutely. Pictures are coming, but it's a bit of a dogs breakfast when I opened it to have a look. The previous owner installed a newer Alpine 102E and also installed a VDO MS5400 Nav system.Originally Posted by TheTree

Since you have a MY99 with the alpine head unit the nexxia lead will work just fine.....
..... Wiring a head unit in the back into the car system would be a nightmare I reckon
You could of .....

It does work and integrates to the steering wheel controls, but it's not even close to 'professional' standards. Perhaps very few people in Australia had the knowledge and skills to install this equipment.
At the moment the subwoofers are shut down or broken and some unusual homemade electronic board in the audio system behind the console, so I would appreciate any advice on what it is and what it does, as this is still relevent within this discussion as I have pulled out part of the console and dash to remove my heater matrix.
Regarding about that matrix, I promise to start another thread as I have bought a new matrix and I have some concerns with its contruction.

I just sorted out most of a dogs breakfast behind my radio as well
Mine had the third plug the "C" connector cut off completely and some wires hacked and soldered back in
I managed to work most of it out but will have to nut out some more wiring when my steering wheel control adaptor arrives.
I found this P38 pinout on the a thread in rr.net which does not seem to quite match mine, I think it may be for a Alpine head unit.

Yours looks professional compared to mine
The little board in there is mot likely the attenuator as described on this page
Aftermarket Head Unit Adaptation for Range Rover 4.0/4.6
The lack of a subwwoofer may mean it's not connected (it's the last 2 pins on that rather rare 10 pin ISO connector as per the diagramme) or the head unit does not have a subwoofer output
I will say however that adding an aftermarket head unit greatly increases the amount of spaghetti in there!

This is a 9 out of 10 on the hack scale!
The "B" connector has been completely cut off and three of the wires were soldered and spliced into the "A" connector wires with a massive loop of cable and in inline fuse holder
These three wires seem to power the dash and the fuel gauge as we found out! Could this be the reason for the fuel gauge weirdness in some models? The other chopped off wires are the steering wheel controls
Also the connector to the head unit had it's end hacked out so the 10-PIN connector would go in itOf course the subwoofer was not connected at all!

SupporterGarry, that circuit board simply drops the voltage supply from speaker voltage to ideally 3 or 4 volts for the door amps.
I've just put a clarion nz502a, though its the fourth unit I've put in.
Througout the various head units, 3 or 4 volt pre-outs work the best, and they need to be independantly ground else you get an earth loop.
With 1 volt pre-outs I couldn't get any volume, and at speaker voltage turning up to 1 would be to loud for general listening.
