Its awesome, just too biG!

This does everything i needed it to. Works like a charm. ease of wiring for sure! however instructions lacked but its pretty self explanatory.

Anyway my only problem is i have a hummer h2 and for a such a big vehicle the space you have where the radio goes is extremely limited!!
This this is so long! wires are also very long! made it very difficult to fit everything in there.

Other than that it was good!
