No Audio issue since MCU2 upgrade


Jan 5, 2017
York, PA
A new recurrent issue came up since MCU2/HW3 upgrade coming from MCU1/HW2: every 2-3 days I get in the car in the morning and there’s no audio whatsoever; no music, no turn signal clicks, no navigation voice, no chimes, no voice commands voice... the only way to fix it is MCU reboot. It never happened before the upgrade.

Wondering if anyone else who upgraded or who has MCU 2 has the same issue and how it was resolved. Thanks

I have. It was more of a delay in the audio. I'd activate AP or lane change signal and the audio would lag behind a few seconds. Rebooting the MCU solved this. I haven't driven much since getting MCU2 but I have not observed this issue so far.
