One thing I've always hated about most head units is that, once shut off, the shuffle feature is turned off (ie. I'll stop at a store, and come out and have to press shuffle again to get it randomize).

I believe the unit remembers to shuffle, but I would also like it to remember *which tracks it has played already*. That way I won't get repeats between boots.

It may do this already - I would just like to confirm. I don't know because my install is taking forever... :)
