I came in with, what I assumed would be, a $600 repair on my husband's navigation/map computer. Don went out of his way to check a couple "longshots." He and his guys were smart enough to find the problem without ripping apart the dash of the truck! They could have easily told me it was an expensive repair and they didn't. I got out of there for $75, completely satisfied. I would recommend Soundwerks to anyone and everyone!
