Hi there. I am new to this forum, but have owned a TT XXL for a little over a year with no issues. As I attempted to update my maps I ran into some difficulties. It took me 3 times to finally download an updated map, and I have the maps saved on my computer in HOME, but when I plug the device into my computer I get a message telling me it needs to be formatted. So, of course I obeyed and started the formatting. How long does this take? It has been running for 13 hours and the green line is still less than half way. I am formatting at FAT32 and default settings. Any ideas? Should I do something different?
