Thanks for the info. Looks like I am not the only person with a CDR-30 that loses its presets. Also, this is the car's 2nd CDR-30 as on the 1st one the CDP didn't read CDs.Same thing happens to the CD-R 30 in my new Boxster Spyder. At least 5 or so times since I picked it up earlier this month. I figured I'll bring it up with the dealership when it goes in for it's first service, but I'd be grateful for any information I could get prior to that.
