Various Bluetooth Audio functions are no longer functioning with customer’s phone such as ability to change the track using the steering wheel controls. These concerns can be caused by changes made on the customer’s phone. Make sure to inquire with the customer if the connectivity concerns occurred after receiving an operating system update on their phone or they have restored their phone data/settings recently. RECOMMENDATIONS Check for Tech Tips and TSBs which may address certain Bluetooth concerns with the vehicle’s multimedia system. Confirm known good phone in customer’s vehicle. If known good phone experiences the same condition the vehicle system should be diagnosed using the vehicle’s repair manual.

If the condition continues to occur only with the customer’s phone then the next step is recommended before handset replacement. The customer should do this themselves as it will cause data loss on Android and full system reset on Apple devices. Customer should first backup their phone and data before proceeding. For iOS 7.0 and later, the customer can go to Settings, General, Choose “Reset all Settings” For most Android phones, the customer can go to Settings, Backup and reset, “Factory data reset”. Customer should first try Bluetooth operation before restoring their phone. If Bluetooth issues are resolved then some software setting or program was causing the concern. If condition is not resolved then the customer should contact the phone carrier or phone manufacturer for support. LINK REFERENCES 1.
