I like the Montana, BUT, I had one replaced due to its inability to guide me through busy interchanges and large cities.

The new one was a bit better but still after a long days ride, when I came into a city it was too slow and I missed many a turn because it could not direct me to where I needed to go. Once I entered the straight lines of Kazakstan it worked fine.

The only bits that failed were the 'routable' directions, picking a waypoint in 'direct' mode was never an issue.

THEN, the screen cracked, exactly like the chap above. I am now stuck in Thailand with the dead, as far as I am concerned, still under warranty GPS, in a bag ready for a talk when I can find a Garmin rep.

I bought a $60 cheap Chinese unit to get me around SEA, it uses the iGo system.

I am not sure the Montana is robust enough for the work it has been through, it was in the Rugged mount at all times, except when I was hand held Geocaching.

If I could find a new screen I would be happy to still use it, but I am not sure it is worth the money until they correct the mapping and Nav errors of which there are plenty.

The Montana is extensively covered over at ADV Rider forum, it is now at time of writing this over 5550 posts and has been going for longer than a year

I would suggest you read most of this stuff and form your own opinion. Most of the issues that occurred in the past have been documented and fixed. BUT, a lot of good stuff that previous GPS models had were never brought to this model and this is still a bone of contention with most of the power users of this model on this site.

I bought mine after reading some 2000 posts as they seemed to have the issues sorted, now I wish I had not spent the money on the 650T. Some people have had their units replaced up to 3 times, some have been using them without any problems, so for me this is an indication the quality control is not there and they have tried to fill this model with too much stuff which is no doubt conflicting.

Cheers from Thailand
