1515 tried to update us and europe maps - not enough space. Bought a 32 SDHC card (as recommended by TT) - installed it - TT formatted it - not recognized when I try the icon it says: insert memory card. Looked on the device - it shows the card and available space. Meanwhile downloaded something twice for several hours - first time it stopped about 95% - second time the create space screen appeared. In addition it seems to sometimes "connect" to PC and loose connection. On the device the message: something went wrong - service not available ... appears and goes away again.
I have yet (in several years) have ANYTHING go right on the TT website. Tech support tries and keeps asking questions until they find something I can't do and then pounce and declare that as the problem. Example: try a different computer - didn't work same problem - try a third computer - don't have one. I am nearing the end of the second week trying to update my maps - might try smoke signals ...
Any help is appreciated.
