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 known good phone does not experience the condition in the customer’s vehicle, no repair
should be attempted to the vehicle. The following steps can be performed to resolve the most
common phone side issues.
o Confirm if phone has been tested for phone compatibility by going to TIS homepage and
Clicking on Toyota Bluetooth® Compatibility Information link under Service Resources. If the
phone did not pass compatibility testing for the customer’s concern, please explain the
phone’s limitation to the customer.
o Disable and re-enable Bluetooth® on the phone.
o Perform “Delete all personal data” on navigation/display audio equipped vehicles.
o Delete all Bluetooth® paired devices on the customer’s phone.
o Soft reset customer’s phone or pull the battery out of the phone.
If the condition continues to occur only with the customer’s phone, then the next steps are
recommended before handset replacement. The customer should do this themselves as this
will cause their customizations/network connections to be lost.
o For iOS 7.0 and later, the customer can go to Settings, General, Reset, choose “Reset all
Settings”
o For most Android devices running 6.0 and later the customer can go to go to Settings, scroll
right over to the Personal tab, choose Backup and reset, then “Reset network settings”. For
older devices which do not have this option you will have to skip this step.
o For Samsung phones running OS 7.0, go to Settings, General Management, Reset, then go
to “Reset network settings”.
If the condition continues to occur only with the customer’s phone, then the only step left before
handset replacement is full system reset. The customer should do this themselves as it will
cause data full loss on both Android and Apple devices. Customer should first backup
their phone and data before proceeding.
o For iOS 8.0 and later, the customer can go to Settings, General, Reset, choose “Erase all
Content and Settings”
o For most Android devices running 6.0 the settings screen is divided into Tabs. The customer
can go to Settings, scroll right over to the Personal tab, choose Backup and reset, then
“Factory data reset”.
o For Samsung phones running OS 7.0, go to Settings, General Management, Reset, then
“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.
