I'm trying to decide whether to buy the Garmin Montana 600 or whether to wait and get the Monterra.

Until this week, I had decided to wait for the Monterra to be released. I like the fact that it has both GPS and GLONASS, as I expect that would improve overall accuracy. However, the Monterra still hasn't been released and the Garmin website is still showing a 5-7 week waiting period (it has fluctuated between 3-5 and 5-7 weeks for the past couple of months). I suspect that they may push it out in time for Christmas but I'm getting more concerned about the bugs in a new release model.

I want a Montana/Monterra for my 2014 trip through Russia, Mongolia and the Stans (driving a Land Rover). I plan to use open source maps (and Walter's waypoints). Whilst the trip won't commence until April 2014, I want a unit in my hands earlier so that I can get the maps installed, etc.

Considering the likelihood of new-release bugs and the resulting firmware updates that will occur with the Monterra, I am now leaning towards buying the tried and tested Montana 600. At least I won't have to worry about bugs with the Montana - and it is retailing at $450 in the US (a $200 saving compared with the Monterra). I'm heading over to Miami next week, so I could pick one up then.

Before I make a final decision, I'd be interested in hearing the opinion of others, particularly those who already own the Montana.
