Note:
•
•
Unexpected loss of radio audio (radio goes silent/no sound for no reason): See #1 below.
Other Blackberry® phone / Bluetooth® issues: See #2 through #8 below.
Condition/Concern
The following is a list of conditions that a customer may comment about. Review the numbered Conditions in the list
below and then refer to the appropriate numbered Correction that follows.
1. Shortly after the customer powers the vehicle and is listening to AM/FM/XM/CD/AUX, audio is lost and the
customer can no longer hear the music/audio playing. Music/audio fades to silence for no apparent reason. A
Blackberry® phone is paired to this vehicle, and is within range of the vehicle when this issue occurs. The
customer will not know that the phone is causing the loss of radio audio.
2. When using the Blackberry® phone, the Bluetooth® function fails to connect, does not consistently connect or
won't connect to the vehicle even after the customer tries to force a connection from the phone.
3. Audio is not heard in the vehicle with a Bluetooth® phone call although the function previously worked properly.
The customer has to transfer to the phone handset to listen to the call.
4. The Blackberry phone with Bluetooth® on will display an hourglass as if it was connecting to the Bluetooth®
feature, but the customer cannot complete the connection to the Bluetooth® feature.
5. The customer receives a continuous request on the cell phone to connect to a device that is no longer shown on
the phone, due to the pairing being deleted from the phone but not from the vehicle.
6. The Blackberry® phone using Bluetooth® will not complete a call when dialing a number from the phone or
complete a call through the vehicle's stored nametags in the voice recognition system.
7. With a Bluetooth® call with a Blackberry® phone, the customer ends the call by pressing the Blackberry® phone
End Call button and the vehicle displays Private Call.
8. When using the Blackberry® phone, an incoming call may ring 2-3 times before the ring is heard in the vehicle.
It may take multiple presses of the steering wheel controls to answer the call, or to make an outgoing call.
Recommendation/Instructions for Condition #1
Shortly after the customer powers the vehicle and is listening to AM/FM/XM/CD/AUX, audio is lost and the customer
can no longer hear the music/audio playing. Music/audio fades to silence for no apparent reason. A Blackberry®
phone is paired to this vehicle, and is within range of the vehicle when this issue occurs. The customer will not know
that the phone is causing the loss of radio audio.
The occupant’s Blackberry® phone is sending a phantom message to the vehicle, telling the car that it is in an active
call and needs an open voice channel for the conversation. The vehicle audio system is complying with the phone’s
phantom request. Radio audio is lost as a result so that the conversation can take place via the car’s audio system.
The problem is the customer has neither placed nor received a call, so radio audio is lost unexpectedly.
1. Confirm the issue and the cause: Take the Blackberry® phone into the car. Power on the vehicle and make sure
the radio is on (music is playing). Wait a few minutes. Once the Bluetooth® connection is established between
the phone and the car, you should lose the audio. You may see a Bluetooth® icon in the top right of the radio
display screen. Now push any phone hang-up button in the car (on the overhead console, steering wheel, or
center stack). If you hear a voice say “call ended”, then you know that the phone is causing the problem.
2. Let the customer know that the phone is causing the issue. Advise the customer to check for software updates
and download the latest version of software to their phone.
3. Do a soft reboot on the customer’s phone.
• Remove the battery from the Blackberry® phone for at least 10 seconds.
• Reinstall the battery.
4. Verify that the problem has been eliminated.
Note: Inform the customer of the cell phone reset process since they may need to do it again sometime in the future.
Recommendation/Instructions for Condition #2
When using the Blackberry® phone the Bluetooth® function fails to connect, does not consistently connect or won't
connect to the vehicle even after the customer tries to force a connection from the phone.
1. Inspect the customer's phone and verify that the General Motors vehicle is selected as a: Trusted Device to
Always Connect.
After the phone has been paired to the vehicle, verify the setting in the phone is correct by:
1.1. Displaying the phone's: Bluetooth® menu.
1.2. Observing the: Device Properties of the General Motors vehicle that is paired.
Note: Selecting General Motors as a trusted Bluetooth® device enables the phone to allow the vehicle to
automatically connect to the phone when the vehicle ignition is turned to ON/RUN or ACC/ACCESSORY.
1.3. Verify the item displayed is: Trusted: Yes.
2. To guarantee future customer satisfaction, advise the customer of the following phone pairing instructions (print

turned to ON/RUN as indicated in the vehicle's Owner Manual.
Recommendation/Instructions for Condition #3
Some customers may comment that they were successfully using Bluetooth® in their vehicle for days, weeks or
even months at a time, but suddenly the phone no longer allows phone calls to be heard in the vehicle.
A typical scenario is when a call is being made or an incoming call is received, the Bluetooth® call is ringing in the
vehicle but when the call is answered there is no audio. The customer has to transfer to the phone handset to listen
to the call.
1. Remove the battery from the customer's Blackberry® phone for at least 10 seconds.
Note: Inform the customer of the cell phone reset process since they may need to do it again sometime in the future.
2. Install the battery in order to reset the cell phone.
3. Verify that the condition has been corrected.
Recommendation/Instructions for Condition #4
The Blackberry® phone with Bluetooth® on will display an hourglass as if it was connecting to the Bluetooth®
feature, but the customer cannot complete the connection to the Bluetooth® feature.
Set the Blackberry® phone Bluetooth® Options to the following:
• If the phone has a Contacts Transfer feature, “Contacts Transfer” should be set to: disabled.
• If the phone has an Address Book Transfer feature, “Address Book Transfer” should be set to: disabled.
Recommendation/Instructions for Condition #5
The customer receives a continuous request on the cell phone to connect to a device that is no longer shown on the
phone, due to the pairing being deleted from the phone but not from the vehicle.

titled: Deleting a Paired Phone.

2. Install the battery in order to reset the cell phone.
3. Verify that the condition has been corrected.
Recommendation/Instructions for Condition #7
