I would like to have the video feed from the OEM backup camera display all the time on a rearview mirror monitor. If the connections from the camera are unplugged from the Uconnect and plugged into the rearview mirror monitor (with separate 12v power to the monitor), will it work? Is the OEM camera supplied with power when the ignition is on or only when the vehicle is in reverse? Will the vehicle's system "complain" that it cannot find the video feed in the Uconnect? [The vehicle is a Winnebago Travato 59K, so the rearview mirror shows just a tiny "slice" of what's directly behind the vehicle] Thanks.
