I have a TT Go 720 which when left unused for a week or so seems to lose my favorites and home details. I have replaced the battery and the device is holding charge. any ideas? is there a secondary internal batery for memory???? Help!
all this data are stored in map folder. File name: mapsettings.cfg.
It looks like internal memory is faulty.
Do backup of Your TomTom internal memory then format it (fat32), then copy all files/folders back, but first delete file MapSettings.cfg from map folder.
If it do not help, try this:
Copy all files/folders on to SD card and put it in to your device. System will start from SD card, not internal memory and should remember all datas (favourities and home details).
