Ive got a V2 and Im happy with it. MP3 sound quality is very good, as long as you use the RCA outputs direct into the head unit, and NOT the FM modulator which is crxp, it causes some background hiss and distortion. Also with the FM mod you cant get the RDS/EON traffic announcements when the head unit is tuned to the mStation. It great not having to have CDs lying around in the car and getting scratched, and having such a large choice of music in the car - you can store your entire CD collection on it, provided youve got the time to input them in that is. It never jumps or skips, and itll play MP3s at up to 320k, which is not far off of CD quality and certainly good enough whilst on the move in the car. At around £425 though (for the 60GB version), its probably only justified to those who have a large MP3 collection in the first place, and a decent PC to dowload them to the mStation. The main unit is not particularly attractive to look at, but its mounted totally out of view in the boot so that doesnt matter. The only extra thing you have inside car is a small head up display with IR receiver and a tiny remote control unit.
