Entering the code on the Uconnect 8.4 RM4 VP4 JP
The code goes into the unit itself, not into the car's menus.
- Turn the ignition on so the radio powers up and shows the locked screen.
- A four-digit keypad appears on the display.
- Key in the code, one digit at a time, left to right.
- There is no separate OK button - the radio checks the code on the last tap.
- A correct code clears the lock screen and the audio comes straight back.
Things that can catch you out
The screen shows a wait timer
After a few wrong entries the radio stops accepting codes for a while - cutting power only restarts the clock. 30-minute WAIT after three wrong attempts.
Where the number actually is
The serial is on the unit itself, not in the vehicle papers or on the dashboard. Top of the chassis label.
The radio locked itself again
Expected behaviour: the security system trips again whenever power is cut. Battery disconnect.
