^ Audio devices including iPod Touch, iPhone 4, and some others will drop out and/or skip during streaming audio session.
Note:
HFM part numbers that end with AK will receive the following enhancements.
- Reduced "device Reading" wait time after connecting a device to the remote UBS port.
- Call/Dial separation improves upon names being recognized as phone numbers.
^ Improved sound quality during Bluetooth streaming
^ Increased iPOD and iPhone compatibility
^ SMS messaging support via MAP protocol (not all phones support the MAP protocol)
^ Added "None of These" and "Correction" to the phone book prompt menu for better handling of similar names
^ Previous button will return the song currently being played to the beginning of the track

not selected.
Note:
USB mode resume will no longer "resume" after ignition OFF.
Diagnosis
Using StarMOBILE, determine the HFM part number. The HFM part number can be found under Module Information for the HFM.
Is the HFM Part number one of the following: AF/AG or AK?
Yes: Perform the Repair Procedure.
No: This service bulletin does not apply. Further diagnostics may be required. If the customer describes the symptom, perform the Repair Procedure.
Repair Procedure
Note:
^ One USB Cable 7B0051446 may be used to service multiple vehicles (figure 1).
^ Remove knee bolster to gain access to HFM module as seen in figure 2.
^ Temporarily install USB cable P/N 7B0051446 into the HFM as seen in figure 3.
Prepare USB Memory Stick
Note:
Preparation of the USB memory stick involves a proprietary module flash application to a USB memory stick. The USB memory stick is then used to flash update the Hands Free Module.
Verify that the Hands Free Module is functioning as designed. If DTC's are present, record them on the repair order and repair as necessary before proceeding further.
^ For the AF/AG update, open the AF/AG uconnect.zip file from ServiceNet and download the uconnect.udp file to a blank USB memory stick.
^ For the AK update, Open the AK/AB uconnect.zip file from ServiceNet and download the uconnect.upd file to a blank USB memory stick.
^ The files can be found by selecting Technical References, and then Technician Helpline.
Perform Software Programming
Note:
Install a battery charger to ensure battery voltage does not drop below 13.2 volts. DO NOT allow the charging voltage to climb above 13.5 volts during the flash process.
In the event of a software programming failure the system will respond with an audio prompt indicating "Digital Signature not recognized" or USB Mass Storage device not compatible". If this should occur, download the
software programming to the USB Flash Drive using a different USB port on the computer. If this does not resolve the issue use another brand of flash drive.
Damage to the HFM may occur! DO NOT interrupt vehicle power, cycle ignition, or remove the USB memory stick while performing software programming. If the software programming is interrupted and an audible prompt is NOT heard after pressing the radio's phone button (with the radio volume set at volume or higher, the HFM module will need to be replaced. If the software programming is interrupted and an audible prompt IS heard after pressing the radio's phone button the flash can be reattempted.
