i have hooked up rio to pioneer via the ip-bus aux in adapter for the pioneer and i can't seem to figure out a way to turn on the aux input function for the pioneer. both units power on fine. also i have noticed that if i turn my keys to acc while the rio is still in the dock, it'll start to boot which i is normal. but if i take out the keys immediately the rio still continues to boot and it'll even go into it's playlist and start playing songs and stuff. is this normal or did i wire up things the wrong way?
