i have grounded my parking brake wire and nothing changed. what else may i have to do to bypass the security lock on the dvd and nav while moving? thanks

read the other posts under hacks/mods in the n2 section...its not as easy as grounding the parking brake...you have to either solder 2 points together, or take the safer route, and use a 'circuit writer' pen, which they sell at radio shack, which you can use to 'draw' a line with conductive ink between the 2 points; no heat involved, much less chance of botching the mod....look at past threads on how and where to find the 2 contacts
