I have had my Montana for about 18 months and have only just started using it for hiking, after my HP IPAQ (running WinCE) died.
It has taken me sometime to understand BaseCamp; mainly due to the terminology used compared to the program I have used in the past.
To say the learning curve has been steep (and frustrating) is an understatement.
Anyway, I have created a route in BaseCamp and sent it to my 700i.
I have audio alerts enabled and "Direct Routing" enabled (since "Direct Path" as a course navigation method does not work as anticipated).
"Lock on Road" is also disabled. This "feature" was also the source of much frustration as the option to enable or disable it is not available in the GUI when "Direct Routing" is enabled. If "Lock on Road" was enabled when "Direct Routing" is enabled, the map continues to "Lock on Road", but now you have no way disable it!!! You have to disable "Direct Routing", disable "Lock on Road" (which is on another menu), THEN enable "Direct Routing".
With all that sorted, on my 700i I go to "Where To->Routes" and select the downloaded route. I see my route plotted on the map as a direct path between points. All good so far.
I then select GO. First off, I don't see a lead (pronounced "leed") line into the next waypoint. I have two of the data fields (on the map) set to "Distance to Next" and "Next Point" (so I can see which point I'm navigating to and how far it is) but I don't see an indication on the map as to the direction (i.e a lead line).
This is a big problem if the next point is no visible on the map (i.e the trail meanders through terrain away from the next point). This becomes a bigger problem if our route is a "loop" and we come to an intersection we will return via on our return trip. Which way do I need to go?? I can muck around with map zoom, etc to find out but it is much easier with a lead line to the next point.
As an aside, If I "Go" to a single waypoint outside of the route, I get a lead line.
Another issue is I don't get audio alerts when nearing a point. Once I get within the "proximity range" of a route point, it switches to the next point in the route but I get no audio alert. The only alert I get is when I am approaching the destination of the planned route. I frequently put the GPS in my pocket whilst hiking so alerts on waypoint change is critical to me.
I have a few other usability issues but will save them for another post.
