How long does it take for the navman f10 to charge using the usb cable?

Question

Just bought one and the screen shows that they are connecting (usb and navman) and the battery light is orange, does this mean that it is charging? It also doesnt work via the car battery so this is my only option at the mo as it doesnt come with mains charger!

Answer 1

the first time it takes quite long then afterwards if there is a low battery to full baterry aprox 20mins maximum
