My Bluetooth recently stopped working, I called UConnect and they told me I needed to download the update by USB. So they emailed me instructions. I downloaded the uconnect.upn file to the USB and when I plug it in it says device empty. Any suggestions? When I extracted the zip file to the USB it wasn't 5 files like it suggested it should be in the email they sent. Please help. I really don't want to pay $80 for the dealership to do it.
