Special thanks to Randode for figuring this one out I just want to clarify with pics.
This mod is yours and if you screw it up I’m sorry.

1. First take off the bezel around the radio



2. Remove the four 10mm headed bolts from the radio and remove, being careful not to pull the wiring too hard.



3. Looking on the back panel you’ll see the red arrows pointing to the wires being modded:

a. The red/white wire (parking Brake input)
b. The purple wire (VSS input)


Or


4. Starting with the red/white wire.
A. Cut it about 12” down the harness and tape off the harness side wire.


B. make a length of wire for the grounding to the radio like this:



C. I used this ground point:



D. After you cut the red/white wire splice the end going from the radio to your new piece


E. install the new wire now formed to the bolt with a 10mm wrench



NOW WE’RE HALFWAY DONE!!!!

5. The purple wire



A. I installed a switch in one of the blank panels by the trac control



B. Add to lengths of wire about four feet long to each post of the switch



C. I routed the wiring thru here, popping this panel off to gain better hand access


D. Routing the wires up thru the dash to the back of the radio I cut the purple wire about six inches away from the radio while the connector was unplugged. I then stripped the wires and added the purple wires to the two wires on the switch.



E. It doesn’t matter which side the wires go on;



Then I put the whole thing back together and now can have a passenger use the navi controls while I drive or watch a movie or whatever.

Nice post! Anyone know what the toggle switch is for?
The switch is to turn the VSS off so you can enter a address on the Navi unit while driving and to watch DVD's while driving also....

works great thanks for the pics, if your installing the nav yourself just ground the pkb wire (red/white) instead of running it under the rug to the ebrake. and for the vss purple wire you can get a really small toggle at radio shack and put it just about anywere.

Hi
I just did this and when you have a route already in and you cut the signal to enter a new destination while driving and then turn it back on, it is off while driving for a long time

I thought the satellites would correct your position once your re-activated it again.

What have you found when you do it.
