Route names appear double after copying to Tomtom
Had some routes imported. Because I changed them, I deleted them in the TT, and also via Windows Explorer. So the TT looked empty. After have copied the new made routes to the TT and after having imported them, I opened the route list. All the routes appeared to be double in the list. For instance: Dalen - koffiestop.gpx, plus Dalen - koffiestop (1). This is a phenomenon that I knew from Garmin Zumo 660, and its cause was that in that case I had forgotten to erase the original route from the Garmin drive. I have looked into the TT but can nowhere find any remaining old files. Nonetheless the seem to be stil hidden in the TT. How can I erase those hidden routes? I have a micro sd in the TT, but it is empty. Thanks.
