A few useful features I discovered recently using the Montana:

Alarm. The unit can be set to activate itself when the alarm goes off. I used this as part of battery saving measures when there is a long leg with no deviation, eg 100miles to next turn; if I think I am averaging 50 mph set the alarm for say +1hr 50mins and it automatically switches the unit on and you will be within 10 mins or so of the turn.

Profiles: if the routing setting is for "prompt" you will not be able to change preferences, avoidances, etc in any profile. You need to select a preferred routing profile then you can change those items.

Reducing screen brightness to the lowest you can get away with (50% for me) and setting the screen to off after say 1 minute are probably the most effective battery saving measures (after switching it off). On mine, single tap the power button brings up the status screen and the brightness is adjusted on a slider (the single tap can be configured to bring up other features though).

The battery will vibrate loose on rough roads. Wedging a folded up business card between it and the battery cover worked for me.

Drag and drop items onto the home screen from the setup menus is useful.

Now I am learning my way round the Montana it is one of my all time favourite gadgets. I wish I had got the 650 with camera though.

On the question of viewing a big route without panning right out, if you tap the bar at the top of the map screen (when its got an active route) that desribes the next turn it will bring up a screen with all the route directions in separate fields. A further tap on each field will open the map for that particular turn which can then be panned in or out. Not perfect but it works for me.

The update that allows removal of that annoying red pin sounds like a good step forward.
