These firmware versions disappeared very quickly when everyone write about the authification problem. For the Oregon600 the 3.70 version even not excist for Garmin at the moment. Is goes from 3.60 to 3.80. The same way for the Montana.
So that problem was rather a mistake of Garmin than a structural solution to read an additional protection I guess. As a write before, with my Oregon600 and FW 4.10 I don't have any problems until now.

So, now comes again the other question: the new Nuvis and Zumo's and 64-series and Edge 1000 have a structural protection mechanisme build in the latest firmware ? See my questions at post #11
