Worst experience with install shop ever!.
Avoid them if you want a quality install behind the dash with everything working. These guys are very condescending and arrogant. You know nothing and they know everything. If you are dumb and will not check over the work they did, then maybe this is the shop for you. If you just want it to work and don't care about the rats nest left behind (especially if an alarm install), then you might get by, but I would move on to a better shop that values their customers and their opinions on what is being done to their car.
