I had one, and gave up on it. The vibration killed it after about 2 months. So I went back to a Cassette player that had a CD Input. And from that I use a shock mounted "NOMAD" player for MP3s. I can set up what I want, play 30 hours or more of music from a pre-selected program, and not worry about it.
The Nomad is very durable and shockproof and I get to take it home.
Works for me.
