I researched this unit from the manufacturer down to the tiny corner audio installation shop, read every review I could see on the Internet, even went as far as listing all the pros and cons. I had a really cheap planet audio that worked great, but I needed up grading. I settled on this unit for price and features and had it installed professionally. It lived up to everything I wanted and then some. However, in my rush to have this unit, I paid nearly twice the Sonic price, and paid separate for the install kits! Should have got it at Sonic and saved a few hundred bucks. This unit works better than advertised.
