: VSS wire for Navigation on my '04 EXT

05-07-07, 10:53 AM
I hooked up a switch to the green/white wire on my '04 navigation.

It works great and it does unlock the nav so i can use it while driving.

The wierd thing that happens is:

When i hit the switch while driving, my speedometer pin drops all the way down to zero! The RPM is still working though.

Then if I hit the switch back, it pops right back up to where my mph is at while driving.

Is this normal? lol.

never noticed that.. the only thing i noticed is that occassionally if you hit the switch while driving sometimes the nav cant find itself and you have to turn the radio on and off to get it working again..

Also, when I hit the switch, there are a bunch of horizontal lines on the nav screen like there's an interference on it... Anybody else have this problem???

I must say I'm having the same thing my nav2go is not working now. just the horizontal lines for over 2weeks. could there be an issue with the main box? or I was thinking about an wire could have came loose but I don't have the instruction to verify wires
