Ok i have searched and searched and read and read. I am installing a rear Audio Video Monitor and just running one video cable to the rear monitor but the question i have is i hooked to Rear Monitor out on the Avic and nothing shows up. I know in the past you had to switch the Rear monitor on is this the case in the F series i cant find it anywhere.. Someone help please. Either my output on the avic doesnt work or the Rear Monitor is messed up.. I am gonna do some testing with external monitors and DVD players but till now could someone give me some insight.. Thank you..

Ding Ding Ding i think i found it. The Rear monitor will only show stuff on it when a DVD is being played and not just the GPS Screen. Can anyone verify this. I dont have the car here with me the wife is not home yet.. She has it..

yes a video (DVD or IPOD) has to be playing, the unit will not show the nav stuff on an external display
