Garmin help with navigation
#21
I think the confusion due to the differences between the 305 and 705.  A track (tcx) on the 705 is a pink line that overlays the path you have plotted.  If you deviate more than 50yds from this path the unit bleeps to tell you and a message appears.

A route (gpx) on the 705 will give turn by turn navigation, however when you load and follow it the unit can try to plot a "better" route for you thereby undoing all your hard work.  There is a way of turning off "autonavigate" but i'm not sure if this cures the problem or not.  I also found the turn by turn prompts a little annoying as they covered up the map

Very possible they are different between the two units, but it's not easy to grasp just in relation to the 305.
Basically a track is not reactive & a route is - again I think.

Garmin never intended the TCX bit to be used, that's the file extension used to record the ride data.
I should play with the TCX thing though as it may overcome the waypoint limit, but I'm not convinced it'll provide the directions as the route does.

Does the 705 have a menu item for tracks?
(I may have been typing "course" when I should have been typing "route" earlier :B)
The 305 has two menu options ">Training>Course" & ">Navigation>Route"

A "track" is what it records (TCX) & if you save that via the Garmin unit it becomes a "course"

The tcx should overcome the limit of points you can plot to navigate against.  I beleive using waypoints within the track you can get the track to navigate using the 705.  I haven't tried this out though.

As for the menu - the 705 is setup just as you describe

The terminology is vague.  I understood "navigation" to mean it would navigate a course i had told it to, however in realitly i think it means it will navigate a course that it thinks is the best route to your final destination.  Confusing  Sad

Can you do that file as a gpx please Nick.
Oddly I don't seem to be able to load it into anything as a TCX Undecided

Oddly i used a gpx on the way home last night to see what would happen and it gave me prompts for some of the turnings but not others

Modified GPX attached.
I've essentially added Waypoint names to your GPX.

I've sort of overdone the naming as I didn't want to confuse you with my notations Wink

If you go load this onto your Garmin, ride to near the start & then use the >Navigation>Routes menu then the navigate option.
If it works the same as the 305 the unit will beep twice then display the name of the next waypoint.
Each waypoint is named with letters & numbers.  The numbers are just sequential & can be ingored.
The letters are your directions as follows:

LT = Left Turn
RT = Right Turn
ST = Straight On

I can't help feeling this is pointless on a 705, but give it a try & let me know Wink

On a slight deviation, does anyone know any software/sites that allow you to edit tracks/courses you have already uploaded?
Ride the Spiral to the end
It takes us to where no ones been

Mapsource allows you to.  I think bikeroutetoaster does too but it works on Google maps therefore its hard to pick offroad routes
