ACTION

Upon diagnosis of a customer report, carry out the following steps:

1. Check that the external media source and/or lead is not at fault by substituting the lead and/or the external media source and listening to playback of music
   NOTE: Please verify with a lead which must be in good condition. Some leads have been known to cause issues due to poor quality cable and connector components used in manufacturing. (An assortment of leads from various manufacturers would be useful to show a customer variation in lead capability prior to sourcing a replacement)
2. Check the external media source socket and connections to the USB are not at fault. (Dusty/dirty/damaged).
3. Check that the connections to the Audio Control Module (ACM) or Infotainment Control module (IMC) are fully latched and there are no backed out pins.
4. If any of the above are found to be at fault, rectify as necessary, then retest for symptoms.
5. Only replace the ACM/IMC if symptoms persist giving a full fault description and analysis for returned part.
