    A quick explanation as to why time and cash are not plentiful to solve this problem. Yesterday I decided to fix the poor aerial reception on the radio of our Hymer 575 2004. It has a Clarion VRX848RVD fitted (remember this bit) which also has a screen for satnav and DVD playback. As I was taking apart some of the dash I decided to fit a tracker, now that I am taking apart more and more of the dash I have decided to fit a reversing camera while access to wiring is easy.
    I was originally looking at a tilting camera but all the ones I have been able to find are either in kits or are about the same price as some kits so now I am looking at a twin camera. I am looking for the camera only as I already have a screen but this only takes one feed. The one I am looking at comes with a twin cable so I would need to combine this into one feed via a switch, either automatically as engage reverse or manually.
    I would be interested to know how others have overcome this problem, specifically using the existing screen from the head unit with it's single feed.
    I have until Friday the 16th to complete all jobs as I doubt I would be in the good books if we tried to travel with the cab in its current state.
    Thanks for any advice.

    Barry.

    Use a simple changeover switch or a relay operated by a reversing light feed. You will have 3 video coax connections to the relay or switch: output to monitor; input from camera 1; input from camera 2. Choose a switch or relay that keeps the coax inners close together and bind all 3 coax outers together. Both cameras can be powered from an ignition-switch-controlled feed - it's just the outputs that are switched. Put the switch or relay into a metal box connected to the coax outers.

    Contacted the supplier of the camera and they can supply a manual switch but suggests that the picture will only be available when reversing due to the way the head unit is set up. Surely it would depend on a signal received so it would just be a case of finding out what voltage is applied or removed to give the signal, mimic that and hey presto it works all the time.
