justgregg Posted December 23, 2012 Report Share Posted December 23, 2012 My installer wired my 2013 Tundra back up cam to my Avic-Z140bh thru the rear view mirror display. There are lines on the display when in back up mode. He hooked up a non avic unit and no lines. I realize that the cam signal has to be reduce in voltage for the Pioneer unit, but he says that tapping off the rear view mirror signal is already reduced. Anybody else try this set up. I know on the Tundra forums they run a resistor from the cam signal to the avic with no problem. Quote Link to post Share on other sites
randomwalk101 Posted December 28, 2012 Report Share Posted December 28, 2012 I also have 07 tundra with 130bt upgraded to 140. No lines on stock overhead screen or on the 130bt for backup camera. Quote Link to post Share on other sites
