Converting Itunes to MP3
I own a Garmin Road Tech Zumo GPS for my motorcycle. I have tied to convert my Libray on Itunes to MP3 files as suggested so I can play music through my GPS. When I follow the instructions from Itunes as well as other sources I am unsuccesful. What I end up with is MPEG-4 audio file (m4a). I download the music to a SanDisk 8 GB which plays through Itunes but when I install the Disk into the GPS it says no "No MP3 files found".
I'm sure I am doing something wrong but I can't figure it out. Any help out there from an old guy with ZERO tech skills.
