If all you need to bypass is the parking brake then just push it one click. If you haven't checked yet you might want to see if this even works, alot of the new navs will cut out when the vehicle is in motion.

yes i know you can press to 1 click ,but light on dash is annoying, and as for the vss wire put it on a toggle switch , nav will not work when switch is flipped of course but maybe video will come up, just need know if there is a way to bypass the brake without light coming on in the dash?? thx alot guys for the hlp :)

It will but using it that way with a factory navigation will mess up your on map location/coordinates and will have to constantly be reset. There is other ways to do it but if you ane not 100 % familiar on how to build raw circuit boards I cannot explain for the safty of your electrical system and computer. sorry but safty first.

NEED TO KNOW WHAT SCREEN YOU ARE USING

Some screens have to see a ground to enable the screen and thats it

some have to see the +12volt side of the foot break and pulsed atleast twice to ground then left connected to ground and the 12 volts off (foot off the break pedal after you pulsed it) THESE WIRES ARE SEPERATE OF COURSE

So what unit are you tring to turn on
