oops, just another new GTD not equipped with a manual
Don't get me wrong, but you should best read your manual. The AID is able
to display the map. Along with the 8" Discover Media you have the choice
between displaying that map on either the AID or the headunit, while with
the 9.2" Discover Pro you can display the map on both simultaneously. Any
way - the AID is able to show maps as long as you have ordered your car
with a factory nav system. I'd recommend trying the chrome rocker switch
on the right hand spoke of your multi-function steering wheel first, but again,
there's a manual that's worth reading.
