I doubt it.

Vehicle wiring has changed from the good old days there a wire carried a signal for each component on the car, i.e. there was a wire which was at 12v when the reverse lights where on, and 0 when not. Now days CAN Bus replaced this, with a basic computer network, where a digital signal is sent on the Bus to tell the reverse lights to switch on, and off. Obviously this is not limited to the reverse light, but all functions within the car. There are normally a couple of Buses some for more important functions like Braking and ABS functions, and other for less important stuff like dimming dash lights. Although CAN Bus makes for a much more integrated experience, and lower costs for the manufactures, I think its introduction has caused so many electrical glitches I wounder if it is worth the effort.

Now the problem with aftermarket headunits is they require individual connections, like the old days, and units like this bridge the gap, but they are primarily designed for simple interfaces. The issue with the parking sensors is caused by Land Rover extending the functionality of a classic headunit by including the beep from the sensors.

I suspect one option to get them working would be to find a beeper from a car which uses a separate unit (VW Touran for example), then create a interface on the CAN Bus, no simple task. Then extensively test it to make sure you have not knocked out your ABS

Hmm the device lists compatibility with Freelander 2. What would it be used for on a Freelander 2?

Thanks

I read on Volvo XC90 forum (XC90 has similar can-bus network) that they installed aftermarket unit, but DID NOT disconnect the faceplate completely. Then they used output from OEM amp to power axillary speaker to produce that sound when park assit is engaged. They did say that CD changer can be removed completely, but the faceplate needs to be connected-they were able to hide it inside the dash. I do not remeber how they were able to mute aftermarket headunit, but that can be done using output from reverse light?

When the faceplate is connected, the car "thinks" everything is working properly and produces signal to OEm amp. which generate sound when reverse/park assist is engaged

Amazing work Gecko, thanks for all of your help

Haven't managed to take those extra wiring pictures yet - I was out and about all weekend so will try and get them asap. Glad it's helpful to you though.

No problem Do you have the part number for the mounting kit? Seem to be having some problems finding it, very tempted to hold off for a while though. I hope to be able to use steering controls and maintain parking sensors etc.

Have you looked into this adapter?

m1964,

I did a similar thing when I fitted a touch screen head unit to my Range Rover.

Removed the CD changer from the glove box and replaced it with the original CD/Radio head unit, which allowed me to change the dash clock and set the trip computer etc.
