MrMazda86, in general, if everything is working well, you should leave the firmware as is. Only upgrade when you have problems.
Now considering you are so far away, it might make sense to work on the upgrade the next time you come by this area, or Ottawa, regardless of problems. I wouldn't go to any special effort at this point though. Just file it away for later -- electronicsguru.ca
I will keep that in mind. I may end up making a special trip anyway because of circumstances beyond my control that will be coming up in the spring so as to avoid any possible issue when I'm not around for a while. What is the cost for this upgrade (if any)?
