CONDITION
Some customers may experience Bluetooth disconnections or loss of SMS Text Message
Functionality on the navigation/audio system with Android phones running OS 4.4 or later. Condition
tends to occur to customers who have many previous text messages on their phones.
RECOMMENDATIONS
1. First pair a known good iPhone or other Android phone running OS 4.3 or earlier.
2. Operate the known good phone and confirm it does not experience the customer complaint to
confirm vehicle system is operating normally.
3. If known good phones above operate normally when connected to the navigation/audio system
then the condition is likely unique to Android OS 4.4 and later.
There are two options to address the condition with customer’s phone:
1) For customers who do not use SMS Text functionality in the navigation system, it is recommended
to do the following:
 Delete the Bluetooth pairing on the navigation system and on the phone.
 Restart the phone (Push and hold power button until pop up screen appears).
 Pair the phone to the navigation system.
 During the pairing process the phone will ask “XXX is requesting permission to connect to your
messages”. Make sure to check the “Do not ask again” checkbox and to select the “No” button.
 Other pop ups on the phone can be accepted or rejected.
