heres some info :

Car : 2004 Aud S4

i think my installer did not tap vss wire, nav works fine but i could not

use the route view and guide view , i can only use driver view and map view and vehicle dynamics. any ideas?

Did you have a route plotted at the time?

if u don`t have a route set then you can not use the other views.

k got you so those two views are available during route guidance .

if u have a route set u can use all of the views, but if u have no route set then u can only use the map and driver views.

u got it?

got it thanks a lot guys.
