will my gps/navi work on z2 if vss is grounded?

Why would you ground it? Just don't connect it if you're not going to wire it up properly

will my gps/navi work on z2 if vss is grounded?

i grounded it so movies could play when im driving? but if it is grounded, will gps not work?

SORRY. it was the lime green wire that i grounded not vss. i beleive that is parking brake sense

you cant play movies while driving on a z2 at all

aaa on the highway there was a movie playing on it?

it won't work once it is calibrated.
