How can I reset the Uconnect 8.4 NAV/RA4 system?

The display on the Uconnect system is just showing garbage, best way to describe it is it looks like a giant barcode. The touch portion still seems to be working since it changes the radio station and stuff if you touch it. Any way I can soft or hard reset the thing? It's Saturday night so I can't just drive down the dealer until Monday at the earliest.

SOFT RESET OF UCONNECT

"Step 1) Put your vehicle into the accessories mode (ACC or RUN) **For keyless start (push-button) vehicles: push the start button twice without having your foot on the gas or brake pedal**
Step 2) Hold down the volume and tuner knob buttons, at the same time, for thirty seconds (or until the screen goes black and restarts).
Step 3) Let go of the buttons
Step 4) Turn vehicle off
Step 5) Open driverís side door for thirty seconds
Step 6) Close door
Step 7) Restart vehicle
Step 8) Let the media centre load up and see if concern is still present"

Thanks! That does appear to restart the system. Unfortunately for me, the concern is still present.

Hi needforspeed,

Sorry to hear about this! If you decide to visit your local dealership for further diagnosis I'd be happy to offer assistance if needed. Just PM our page with your VIN and let me know.

The reset directions below don't seem to work on my 2018 with the UConnect 4C that has an On/Off button where there used to be a mute button (in the middle of the volume knob). If I hold those two buttons down, the display goes blank as it does when you hit the on/off button alone.

My Streaming WiFi for UConnect Steaming no longer works, so I was hoping to give it a soft reboot to see if I got any improvement.

Maybe on the 2018s it is the mute button and the tuner button to reset and not the volume knob. Did you try that combo?

It's funny you suggest that. Yes, that was the next thing I did. I also followed a recommendation to hold down the up and down arrows for the driver's side climate control, which apparently worked on older UConnect models, but didn't work here.

I would happily buy the shop (service) manuals, but I can only find 2017 service manuals that will not have detail for the new 2018 radios.

This is what I got from the Facebook group:

Hold phone button (touch screen) and voice recognition button (steering wheel) both at the same time for 30 seconds while vehicle is running. Turn car off. Open driver door 30 seconds. Close door. Turn car on.

That might work if my touch screen was responding to touch.
