1) if you use the search feature to "insert" (i didnt try any other mode yet, but i'm guessing the same), then you skip forward twice, to the song AFTER your inserted song... and then attempt to do a rewind into the end of the inserted song... it completely skips it and goes to the previous.

2) if you're in a started car, and you decide to put the empeg on standby. and then immediately, you stop the car. if you restart your car before the blinking light goes off, empeg starts, but w/ no sound. if i had to guess, the amp didnt turn on. quick standby and on fixed it.
