I noticed a bug when using an Audiolink interface with my new 80gb iPod Movie, when turning the ignition on/off sometimes it would resume playing, sometimes it would not and you would need to press CD twice to get it to start the iPod again.
I contacted RPM and they told me they would send me a new chip with updated firmware for these iPods to fix this glitch.
Just thought I would share this incase it wasn't known and you thought you had to live with that behavior.
