I just got this vehicle and I'm loving it. I purchased from the original owner who optioned it out very well with the exception of the sound system. He go the surround sound option but no mapping/gps but I can set up the Garmin and go. What it doesn't have is USB ports for my music stored a thumb drive. I found a USB to auxiliary plug adapter but don't know that it will work if there's not a means to control and select the albums, artists, etc. Any suggestions on how I can get my digital library to play?
