Hi All. I'm thinking of ditching my 20Gb Ipod & I-Trip transmitter in the car. I want to benefit from my sound system and am considering backing up a lot of my music onto 1gb SD Cards to use with my Sat Nav+ Unit. Any compatibility issues / problems / recommendations I should be aware of? Having never actually used an SD card as a storage medium - would it just be drag and drop for mp3 files and could i create my own separate folders for different albums on the card? Cheers /ubbthreads/images/graemlins/ok.gif Mike.
