H2 Navigation Lockout Override

[Curt Vendel]

Anyone know the color(s) of the input wire going into the H2 Navigation system that senses motion which causes the Nav system to lockout input while the vehicle is being driven???

Yeah, I know its meant to be a safety feature - what the idiots at GM didn't realize is that the PASSENGER could be handling Nav input during driving... There is no override in the software, though I heard there is a cumbersome maintenance mode you can enter, but have to do it each time you start your Hummer, so...

If I detach the tac sense or whatever is feeding into the Nav system, then it will always be available for entry.

Any help would be appreciated, thanks.
