Right Chaps,
I managed to buy the X-Carlink, the seller knocked £50 off for me 'cos I phoned him and had a nice chat. The manufacturer has done some updates, both hardware and software. It now does all sorts of video to the MMI screen and can pass audio to the sound system. I only want it for automating the reverse camera operation. The supplier said that it might now work with my Chinese PAL camera, and yes it did.
Now fully fitted and working really well.
Camera and transmitter/receiver pair as above.
Camera and transmitter in the boot lid, both powered from reverse light supply. The LEDs in the camera body powered by number plate light supply.
X-Carlink powered by a permanent supply and by an ignition switched supply. It also needs a reverse supply, this I took from the reverse light supply by tapping into the loom in the left boot space and running the wire through the car to behind the glove box where the X-Carlink is located. The receiver for the camera transmitter is also located there and is supplied by the reverse supply.
SWMBO has not inspected it yet, but she will give it a good pass mark, really good colour picture, no interference and it switches on automatically. Whatever sound is playing carries on, only the video is replaced by the rear view.
Engaging the backing up gear just does it all for me.
Final cost just over £200.
