Whilst I know that you can have others on an SD card ready for import I can't see why they've done that
Which reminds me, does anyone know how to remove some routes from the SD card?
As suggested I do a route per day, sometimes more so I may have a short / medium / long option to fit in with how I feel / what weather is doing etc.
So I now have loads on there so when I need to import another one I have to scroll down huge list, it is easy to remove them from the unit itself, but cannot find a way to delete of SD Card, only to import from it.
One last point, and this caught me out big time.
If you use the route tool where you click from point to point and then upload it, the click points do not show as waypoints in the unit, so if you need to ammend your plan a little you cannot take them out (without a PC to hand) to make matters worse it will keep trying to re-route you back to the first of these points you missed (or at least it does on my unit)
Took a while to figure this out, it is also easy to click on the wrong side of a Motorway, I did not figure this out until after it had taken me in a loop between junctions a couple of times
I now plan the route only by inserting waypoints as these can be pulled out of the unit in seconds when on the road if you want to shorten a route.
Lastly my unit gets very confused if you have a route which is a loop, or shares a bit of road twice, if I try programming a round trip it tends to tell me I have arrived just as I try to pull away, despite waypoints in route not being crossed, so unless you want to ride around the block your Hotel is on all day set start point up the road a bit.
