Hello, I bought a used Magellan Explorist 500. It will only start in usb mode where it wants you to pick transfer, usb power, ect. This is with no usb cord attached. It is not recognized by windows xp or seven and gives an error that the device has a problem. I have tried a new usb cords. It functions erratic and never gets a signal for the gps. How do I reinstall the firmware without usb? Can the firmware be installed from the sd card? I think this unit is in some kind of safe mode. Please help. Thanks.
