Well, I got 2 months of mp3 listening in before my Sony cdx-f7710 crapped out on me. Now it can't read any cd. And of course I bought it at cardomain.com, which means I have to take care of sending it out to get repaired and wait for a couple months.

BUT, luckily I was easily able to re-install the original stereo, which to my great surprise still has all my presets in it. Even after spending 2 months sitting on a shelf.
