Fault-Tracing Information

Accessory USB unit (AUU) has the function of acting as interface between the vehicle's infotainment system and external USB- and iPod-units. Since later generations of iPod and iPhone use 5 V-charging, instead of 12 V-charging, it is not possible to charge the iPod-battery using the original cable intended for iPod devices. The iPOD-battery can be charged using the USB-outlet, but then Accessory USB unit (AUU) does not handle playback of media stored on the external iPOD-unit.

Check: 

• What charging applies to the external iPOD-unit.
• If there is a need for an adapter cable that supports 5V charging.
