Thanks for the input guys, I will probably disconnect the negative battery lead when the problem becomes more pronounced. I am a bit confused by the term "Master Reset" in the context of the options on my vehicle. I am presuming that disconnecting the battery or pulling the fuse will reset the all the computer driven systems including the radio and sync. As far as determining what version of software I have, I don't have a clue. I have tried to find a reference to updating or checking the software version on the Service Information CD, but, have not seen it yet.
I am cool so far, but, can see the day when this may get frustrating
