So far so good, no lag, screen looks great, radio sounds great. I installed in a 2011 Chevrolet avalanche with the factory amplified Bose system, radio is a little to long so I had to get some angle adapters for the audio cables in the back, and it still stuck out on the passenger side by a hair, almost unnoticeable though, linked below is everything I ordered for the install. The metra dash kit was too small and the scosche kit was a hair to big but it fits ok, so if you take this install on you might want to find a 3rd option. To retain steering wheel controls I had to buy a female 3.5mm jack and hook that between the Pac harness male jack and the key 1 and key 2
