For a while now, when I loaded a course on to Garmin and went to ride it, it was the previous course that loaded. This despite deleting all courses on my Garmin before loading. I managed to overcome this by loading courses direct from my laptop. Now an old course (despite deleting all courses from my Garmin) continues to super-impose itself on the course I want to ride. The result is that two courses appear on the map and it confuses my Garmin which continually tries to re-calculate the route and the navigation is useless.
I have tried going into the files on the Garmin and deleting all old files/courses but this has't worked. All courses have been deleted from my Garmin on multiple occasions but still this old course re-appears like a bad smell and renders my Garmin useless for navigation.
Any help in overcoming this and getting back to being able to use the navigation on my Garmin would be much appreciated!
