By far one of the, if not THE best unit out currently. Install is averagly difficult, check the install guide to see how to bypass your amp. The next thing is running wires to their specified location...which is in the box of directions. Next is to ground out the turquise wire so you can actually watch tv while driving. Most shops charge 150 for the install, but they will ground the turquise wire to the hand brake-making it not going unless its up. To bypass that all you need to do is take it and a screw and ground it to the chassis.
