I was told that this remote was needed to reprogram the monitor whenever power was totally removed from the monitor? Thanks Chris.
How did you fair with the backup camera situation? There is also one other component buried in the dash you may not be aware of: a Niles Audio brand video switcher, activated by the "Camera/Nav" switch on the right-hand dash. I have seen either this switcher or the connections to it be bad, resulting in an interruption of the video signal to the 10.4" monitor's video input card. Of course, if you were to take the dash up and plug another monitor into the cable going into the back of the existing Computer Dynamics commercial monitor, you would know if you have video through the cabling, the distribution amp, and the video switcher to the monitor's input. BE VERY CAREFULL if you attempt to pull the dash up to access the back of the monitor...there are ribbon cables that always seem to be tied up too tight that are easy to pull off and render certain sections of the dash switches inop, as well as the cable that connects the programming tool you mentioned earlier to the monitor control board, and the connector to the dash dimmer knob. The camera is 12v-powered, the monitor has a computer switching power supply that powers it from a 120v outlet buried behind it in the dash. If you get the "no input signal" message, the switching power supply or the 120v outlet are working and ruled out as a problem cause, but not the video input board on the back of the monitor...that DOES have a relatively higher failure rate. Let me know if there is anything else I can help you with.
