I've gone to Pro Audio to get a DvD player in my van and I've also had them diagnose a problem that I was having with my navigation system. Each time I was treated as I was the only customer they've ever had. They took the time to help me out and even answer all of my stupid questions. They did a great job and the kids are happy because they can watch movies and I am happy because I won' t get lost. It's a win-win. I would recommend this business to anyone.
