Technical Background
The customer states that the “radio” may intermittently “lock up” or “reboot”. This can be caused by software
compatibility between devices connected to the infotainment system via USB or Bluetooth. This can also be caused by
the use of aftermarket equipment such as, but not limited to, aftermarket cables and/or charging devices.

Service
Before creating a VTA, find out from the customer if the concern only happens when a device is connected to the
infotainment system via USB or Bluetooth. Note that even if the device functions are not being used and the phone is
connected, the device may still have influence on the operation of the infotainment system. E.g. the customer is
listening to AM/FM but is charging their device via the USB port.
Inspect the customer’s vehicle for signs of aftermarket devices such as brightly colored, braided, or labeled USB
cables, and if they are connected. If they are and the concern is happening, disconnect the cable and retest.
If the customer’s concern is over Bluetooth, please ensure that the customer’s device is an approved device by
referring to the website: www.Knowyourvw.com/bluetooth. If the customer’s device is not on the approved list, please
inform the customer that functionality will be limited and may induce concerns in the infotainment system.
If the customer’s device is approved, and if while using Bluetooth or a manufacturer cable (i.e. Apple) is being used
there are concerns, check the customer’s device for the amount of free space left on the device, and also note if there
are numerous Apps running in the background. If there is little hard drive space left on the device (approx. 10%)
and/or numerous apps are running in the background, this may induce functionality concerns. Have the customer free
the hard drive space and shut down any non-essential apps and retest.
