The other day I realized my Uconnect 8.4 clock was running slow. It seemed the time on the Uconnect system kept creeping back several minutes per hour. I could adjust the time, and it would inaccurate several minutes later. Even after a full system reset. Finally, I stumbled upon a soft reset solution that appears to work. After several days, the clock is back to keeping accurate time.
How I fixed my Slow Uconnect 8.4 Clock
Press and hold the Volume and Tune Knobs for several seconds, then release.
Wait for the system to reboot.
Your clock will now be reset to 12:00. Adjust the time.
If all went well, your clock should now be back to keeping accurate time again. 😉
