cpkdude Posted May 1, 2014 Report Share Posted May 1, 2014 On the x920bt (and others), for the setting "rear camera polarity", there are two choices: GND or Battery Does it matter which one? I believe I grounded my rear camera to a point under the passenger-side wiring panel. I had to do a factory reset to get rid of some Bluetooth problems, and missed noting this setting's selection prior to reset. thanks Quote Link to post Share on other sites
