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 Wink

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

Thanks


It converts CAN Bus to Classic Car Audio Wiring, so you have a wire for Ignition, Illumination, Speed Signal, Handbrake on and Reverse engaged. This interface would work with a Sat Nav / DVD Player or classic audio unit, but it still does not cover the parking sensors. To make the Parking sensors work you would need the headunit to have the functionality to convert the signal from the sensors into the audio beeps, then over lay the sound into the audio channel.

As you can see by the list of cars this interface covers, CAN Bus is a standard, and hence a beeper from another car may be your best bet.

A word of warning. CAN Bus is a computer network, if an interface broadcasts on this network it could stop anything on that network working, this normally is nothing critical, but I wonder what LR's response would be if a seemingly unrelated electrical fault was tracked back to a headunit interface. So choose your interfaces from good sources.

Chris.

You can try this:

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 Smile


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 Smile 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.


The fascia panle part number is listed in the adobe mounting instructions 12.301230-02 , any Pioneer product supplier should be able to get one for you . If you have any trouble go to www.pioneer.co.uk/support/service centres and you can get a list of all the service centres . One of them should be able to help.

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.
