I used a double din kit to install, the tablet is not removable without a lot of work. I have no reason to access the aftermarket radio. All functions are easily controlled with the steering wheel controls.
Trying to do something like this, but I need help. the problem is that i can't fit the nexus 7 into there, because a part of the tablet is where goes the A/C controls, and if I try to put it up, there is the hazard lights button.
