I just bought a 6G Scandisk card for my HCHII. I loaded about 300 mp3's on it and It seems to work OK (well, the mp3's work, I couldn't get any of my wma's to play, but that's not the question here.)

However, every time I start my car now, after about 30 seconds my sound card starts playing. It doesn't matter if I have the radio set to AM, FM, or even if the radio is turned off! It just decides that I want to listen to my sound card and starts playing the most recent mp3 song. Very annoying.

Has anyone else experienced this? Any ideas?

I guess I'll have to take the card out when I'm not using it, but that was the big appeal of it in the first place, vs. an external MP3 player.

Any help appreciated.
thanks,
