I have the Alpine 9811. Its awesome and SOUNDS like Heaven, but the only problems I have with it are the CD Text feature sucks and when I leave the key in the ignition and then turn the engine on, it sort of blanks out and I have to turn off the ignition, take out the key, and put it back in and start up again. Then all my radio settings have been lost.
But the mp3 reading feature is fast and smooth, tilt feature is nice, remote is cool, looks cool, has subwoofer setting, feels like top quality. Recommended.
