Got an autostart installed by them and when I got my vehicle back they did not put the dash board back on, there was cut wire on the floor, and they left my old auto start in my car. When I went back to have them fix that I discovered that they did not hook my auto start up right and the lock and unlock feature did not work. Spend an hour and a half dealing with the mistakes that they had made. I paid $560 for the instal and was not offered any sort of compensation for their mistakes and my wasted time.
