hi.. my car is in the shop, but wanted to see if a new pop-out nav screen will fit in our cars.
Can somebody please measure the following (inches);
-amount of A/C vent overhang
-distance from top of stereo headunit to dash overhang
-height of stereo head unit
-any other measurement i might need to evaluate the above.

thanks, im thinking (hoping) the pioneer screen might work .. ill let u guys know.
