I followed your instructions and burned the iso image to a disc. When i place the disc in my radio and hit map, i dont see a feature that says "Upadate" or anything close. Once the disc is in, It does nothing,it just says "Cd rom disk inserted. Is the disc supposed to update automatically? How long does it take to update? If it is updating, how will i know its working? I did the 2 wire bypass already, just trying to figure out the disc now.
thnx
