Thanks for the info,
I was wondering if there is a thread somewhere that further discuss'

How I can determine which version I have, ie b01 etc...
And if anyone knows if there is actually a hardware difference.

Also, I am interested in any technical info regarding the upgradability of these units.. I'd like to know what is updated when the "wav" file is used to upgrade the codes in the unit, and also if there is a way to upgrade the "operating firmware" (if it is a seperate thing to the "ir code database")

Cheers, Spook8000.
