Release Date:
11/21/2020
Symptom/Vehicle Issue: Audio Mute On All Sources Except AM
Diagnosis: Radio mutes and audio does not return even after a key cycle. The radio audio can
become locked and muted due to a timing issue. AM band does not use the same timing process as
the other modes. Change to AM mode to correct the intermittent concern. Also a 30min sleep cycle
will recover the audio. Or, change the source to AM and then back to the prior source to recover the
audio.
Repair Procedure: Do Not Replace the radio. This is a software issue. A software
enhancement is being developed and tentatively available 1st quarter 2021. Verify software is 34.2 or
higher.
