Head unit slow down? MPG down?

I have noticed a few things with my head unit slowing down.
There seems to be a delay when I push the button to call. It does not queue me to talk as fast as it used to. Sometimes it does not recognize speech until I hang up wait and press the talk button again.
It is a little frustrating.
Also, My MPG seems to have gone from 52 on avg to 48 and some of the power in acceleration is gone???

I wonder if maybe my Music memory stick is too large? (64GB of Music)

Does anyone ever reset the computer with results?
