I really like the memory seats ... but the bluetooth audio works really well and sounds great.
I know I had to fiddle with the tone setting, but now the sound quality of my iPhone through bluetooth audio seems every bit as good as USB or CD ... and much better than FM.One thing I noticed is that each mode(cd, bta, fm etc) has it's own saved tone settings. So it's not a set it and forget it type of system. I had to go and individually calibrate each mode to my liking. I don't know if that would make a difference for you.
