[quote='Jon [in CT]']The change I want most is the ability for a passenger to enter addresses, etc. which the car is moving.
Can your man get his hands on the service manual for the navigation unit that sits under the driver's seat? I suspect it holds the processor that prevents data entry while moving.[/quot
here are the pics and some more info. the wire that needs to be cut for the nav functions to unlock is green/black at the dvd drive under the driver's seat. on the road test this is how it worked.
-when you break the conn. the frozen icons will light up
-the arrow will stop moving on the screen
sec. after you breck the conn. the sat. picks up your location and the arrow will start to move again, but its choppy
sec. after you break the conn. the icons will freeze again, its figured out your still moving and locks you out.
-breaking the conn. again will bring them back
-it does'nt lock you out if your in the middle of entering a destination
this seems to work okay, not flawless but better than nothing. leaving the ant. plugged in does seem to help it repostion you quicker after it loses you.
hope the pictures help with the video input and e-brake lock out
