Today my TTR suddenly switched from the map screen to the 'insert SD card' animation screen, but with the SD card icon with a red cross over it. I pulled over and switched it off and on and it was fine, for about 5 minutes, then it did it again. The card is definitely inserted properly. Now I'm home and it's off the bike, it's fine. I've even knocked it about a bit (!) thinking it may be a loose contact on the SD card but it's perfectly ok now. :-/ So what does the big red cross over the SD card icon mean then?
