I'm experiancing the same issue with using the auto switch on timeout... In the car, when power cycling the unit via normal ignition power on and offs, the setting to which auto visual random is reset to OFF... In fact, each time you go into that menu, OFF is highlighted, although, I believe the readme mentioned something about that was suppose to be that way so that it would always be the same key stroke to change the random setting while keeping the eyes on the road.

In anycase, I'm experiancing the same problem, the randomness setting is always reset to off, therefor, my empeg always defaults back to the first visual I had selected. I haven't tried this on a home power source to see if it works correctly.
