CONDITION
To assist with the early detection and early resolution of audio related concerns you may be asked to
recover MMR data from the head unit.
The following steps are instructions on how to retrieve the data from the system and are only to be
used when requested by FTS and/or FPE.
Important Notes
• An empty 4GB to 32GB flash drive in format FAT32 is required to pull MMR logs.
• MMR is a quality investigation tool not a diagnostic tool for case-by-case support.
• MMR data is saved to the internal memory of the head unit when the ignition is cycled to off. Saving
this data may require up to one minute with ignition off.
• If you just experienced a concern and the ignition has not been switched off, you will need to cycle
the key off and back on one time (in a safe location) before attempting to retrieve the MMR data.
• For Apple CarPlay, Android Auto, and Bluetooth concerns, the MMR data needs to be pulled, or
ignition cycled off (in a safe location), shortly after the concern is duplicated (~5min) to increase
chances of relevant MMR logs to be saved in HU internal memory. If longer time passes after a
concern is duplicated (5+ min since duplication or 30+ min after ignition is cycled off/on), there is a risk
that the MMR log will have been overwritten. In this case, MMR may still be pulled, but it will be less
likely to contain relevant logs for analysis.
• For other type of concerns, like rebooting, screen, connectivity, communication, settings, etc.
MMR may contain relevant logs for a longer period (approximately 5 days of average driving),
depending on driving habits.
• If volume/power knob has been used to restart the head unit, MMR data will be lost. Do not restart
the head unit if you are trying to capture MMR data for a concern.
• If a concern has been experienced, make sure to record the date and time of the occurrence and
provide this along with the MMR data.
• MMR can be uploaded to a TAS case or shared with FTS to be uploaded to OneDrive.
• If MMR is pulled, a report is required, but please DO NOT attach MMR data to DPR/FTR.
