Super noob here. I am just looking to update my maps if possible.

I have a Sony Head unit with a detachable Tom Tom GPS.

It is a DJ serial number. It will only connect to Mydrive, not recognized by Home. Active maps of US & Canada V 8.80.

I saw everywhere that first step should be to back it up. When I plugged it in to my computer (Windows 10) it did not recognize it as something with storage but rather a usb device.

Probably a losing battle but I was looking if it would even be possible.
