Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
To get started, I need to know what type of computer you are using, a Windows XP, Vista, Windows 7, Windows 8, Windows 10 or a Mac.If its a Mac, please check the OSX version as follows, Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
Also, was this a used or refurbished Magellan you just received, or was it new in the box?
And whats the full name brand and model of your laptop as well.. Thank you,
Alright, first things first, lets disconnect the Magellan from the PC
Please press the windows key on your keyboard, hold it down, and press R( the windows key is two keys to the left of your space bar )Onscreen should be a box that says Open / Run . In that box type in,devmgmt.msc and then hit enter...
Inside the device manager we need to find the error-ed Magellan device, it could be in the usb section or in the other section or the portable devices section.. It may say unknown device or have an error symbol next to it.
When you find it, right click it and then uninstall it.
Then, lets slide and hold the power switch on the Magellan for ten seconds or until it shuts off.
Then, restart your computer. Once your computer is fully booted and idle.
If these steps work, let me know and I can help you update the units software next. If these steps do not work, let me know what exactly happens so we can work on this issue further. Thank you,
