This is why I'm trying to spare potential Dynavin buyers the pain of buyers remorse. The Dynavin is junk. Be forewarned. I bought one too!! and had it taken out of my car at great expense.
Take a look at the new Kenwood DNX line.. they are fantastic. I put the DNX6990HD in my car and it has exceeded all of my expectations.
