I purchased an inexpensive Esky wired backup camera camera for use with my Garmin 760. The picture is of fine quality. However, it is not a mirror image on my GPS monitor, so everything is on the opposite side of what the I see in the rearview mirror. This is not too safe. Garmin tells me that there is no "image reverse" setting on the unit, and I find nothing on the camera itself either. Anyone else have a fix for this issue?
