Are you going to call that in to Garmin and see if they say 'user error'?
Greg
I, like you, have been in correspondence with Garmin already.
I mailed in news of the three unforced shut-down events yesterday evening, along with the freezing of the screen.

In a separate mail I also pointed out to Garmin a rather daft feature. On the 660 you can reverse a track, view it and if you want to, save it as a route. A useful tool, some might think. It's only fault is that any wrong tuns you made on the track history will be repeated (in reverse) on the return leg. That I can live with.
You can also reverse a pre-installed route, with multiple via-points, and view it. But you cannot then save it.... which makes the operation futile.
What you have to do is manually reverse each of the via-points, top to bottom, second top to second bottom etc. A time consuming effort,that is prone to user error. Then the 660 will recalculate AND save it.
ie. You have to do something manually, which the device itself can obviously do in seconds.
