It is handy that you can use it not only in the car as a battery charger, but also only the USB part of the house / apartment in the next can to connect the navigation system to the computer. This saves a desperate searching from the cables that are supplied by Tom Tom (car charger cable and USB cable for the PC are separated). It all works flawlessly. Also nice, I find the connection, an adapter for a smaller microUSB this was, if one device to another to connect has.
