Looking for some help with the Media Nav Toolbox. I have downloaded the toolbox, copied the Nav details from the car, connected the memory stick to my laptop and got an update. Plugged the usb back in to the car and I think it has updated. Next stage was to connect the usb to laptop again to finish the update but when I open the toolbox and attach the usb it says no device detected and not logged in. When you click onNot Logged In I get a warning message to connect your device to this PC with USB cable. Anyone know why it is not recognising the memory stick again. Sure I am doing something really stupid.
