So far I've tried disconnecting the battery and hitting the small button for a while and still tried to continue the update as soon as I turned on accessories. I called Customer Support at Hyundai and they just think I downloaded the wrong thing. I am at my desk right now, but they said to remove the flash drive, press the button, and then hopefully it will give you a window to select setup>Bluelink>activate service. I'll let you know what happens, but I have had no luck getting away from the update screen. The person on the phone seems to think that there is no update out and that I must have tried to download a GPS update, but I explained that I did not. This may be a dealer solve haha
