(Just typed this all out once and me flamin' t'interweb went down....)Can you explain why you put it through GPSU? I just map it in Memory map and export the route to the 305
I used to (and still do sometimes) just export the route to the 305.
But there is a 100 waypoint limit which is no good on a long (say 30 or 40 mile) route.
You can get round that by converting the route to a track, exporting the track as a gpx file then using GPSU to export it as a Garmin course (crs) file for loading onto the 305 using Garmin's training software. Whilst it's in GPSU however you can add height data (DEM data I think it's called, from NASA satellites or something).
The disadvantages are that it's a load of messing about (although I find that strangely satisfying) and you don't get an audible indication of upcoming turns.
The advantages of doing it as a course are that (1) that it overcomes the 100 waypoint limit (main advantage) and (2) having added the height data you get a nifty little course profile screen showing ascents/descents and your position relative to that of your virtual training partner. You also get an eta which I can't recall if you get when navigating a route?
(Tracklogs or whatever it's called also does the DEM data but I just don't get on with it...)
Sad but, hey, it keeps me amused (and I can use a real map and compass as well!!).
