that's really cool. Buddy has that set up his 41 GTR. I was playing with it while we went to the bahamas. For someone like me that likes to play music all the time, the large screen with fully functional controls and access to music at your fingertips on the dash is pretty b*tchin. Definitely something I'll look into for the next boat.
