I installed the newest software on my oregon 300 and all the previous problems have seem to have gone away. No more screen lock-up and no more powering off by it's self.
A few of the changes I do like is the fact they added sub-topics to the "where to" categories. Another thing I noticed is the accuracy has been better I see 10 feet or less 95% of the time, even in my truck driving down the road it's 10 feet or better. I see 8 feet on a regular basis.
Anyone else installed the new 3.01 software?
