Could you briefly indicate your process (a) to get the planned track onto the machine in the first place (is this the same as a route??) and (b) split the screen with elevation above it? Many thanks.
I have to say it's more of a party piece than a practical display - I'd rather have a map with 2 data fields any day and you can't have all three at once (map, altitude plot, data fields) though you can have any 2 of those together ...
To answer (b) first - from the map screen go:
Menu* > Setup Map > Data Fields > Dashboard > Elevation Plot* ... and then Back* to return to the map page.
* 'Menu' is the l-h button. * Elevation Plot is the bottom option, scroll down to see it. * 'Back' is the top right button.
All 3 scales (map, and x and y axes) are independently adjustable. To adjust the graph scales, go:
Menu > Elevation Plot > Menu > Adjust Zoom Ranges > waggle joystick to adjust > Back > Back to return to split map.
To answer (a).
To get the 'predictive' effect you would need a planned Track with elevation data included. Typically this would simply be a Track that had been previously recorded on a GPS. Otherwise you'd just see a flat line in the blue area above.
Drawing or autorouting a track in a planning aid such as Mapsource or some of the online services, generally results in a very good track (in terms of following the road) but no elevation info. A few online services do include elevation, but I don't know which.
It is possible to add elevations to any 'dumb' GPX file using this online service
http://www.gpsvisualizer.com/elevation where you simply upload the file and straightaway download a replica with elevations written in. The result is a bit coarse but a lot better than nothing.
The Track, however it is derived, has to be saved out as a GPX file. I then copy this into the [SD Card]\Garmin\GPX\ directory on the GPS. For some reason, I have more success with files transferred onto the card, rather than direct onto the GPS itself - though in theory either should work equally well.
Then you simply use Where To? and choose Tracks then select your Track, to follow it in a navigational mode. (NB if you just colour the Track and display it on the map, but don't use Where To? - again you won't get the predictive effect. Or if you use data fields you won't get navigational hints. Using Where To? with a Track is a more powerful way to do it on these newer models.)
