As Jamie already said, the GLS does support MP3 discs, but its possible the brand of disc you are using might be giving it problems.looks like the gls headunit does not recognize mp3 disks....can anyone else confirm ?
yup just a memorex CD-R with a bunch of mp3s burned on itno way!! so your using a cdr with burned mp3's right ? any different settings on the headunit ?
looks like I'll have to take it into the dealer!
