Roscoe-since you have both units, can you confirm if the size is different given iownedu did not have to cut the opening, but others have?
dimensions are exactly the same. have to cut a little from the top plastic brace. fits like a glove after you do. with the old unit you have the option of moving the face plate up a little on the unit by drilling some new holes for the mounting plate. you will lose dvd/cd function of you do but really, who still has a cd collection, and what fool would try watching a movie while driving a viper?
with the new unit this is not an option. the face plate is connectied via pins to the circuit board of the unit. have to cut.
the old unit BT works flawlesly. the new unit is a better built piece of hardwear and the panal lights look better. the old unit is full brightness when the lights are on, cant adjust them. the new unit also has a preset button to go to the menu page, the old unit you have to hit the tiny little touch screen button in the top left corner with your fat fingers in a bouncing car. the old unit has an external mic for the BT, the new unit does not and in our loud **** cars it sounds like you are in a wind tunnel with the bt while driving. its usable, but not very clear.
the BT was the deal breaker for me. bith do everything they advertise although i have not hooked up the rear view camera. i have played with the ipod and aux input, they work well as does playing music and video from the sd card. no longer need a mp3 player or blue tooth devise in my car. im happy.
