Hi, how do you know for SURE if your 950 needs the upgrade? Ordered 3-17 and it shipped on the 18th. I assumed I was ok but filled out an upgrade form just in case. I figured since I had to include my serial number that if my unit did not need the upgrade I would not get the kit. But I did get it. So my question is... do I, or do I not, need the upgrade? I have not hooked up my unit, waiting for other components ,cables, etc.

Thanks,

Mike
