Symptoms to be Improved:
Loading/spinning icon may appear on the CID and the CCU may reboot or the loading
icon may continue to reappear repeatedly, if the ignition is turned ON (IGN-ON) immediately after CAN bus operation is shut-off.
Bluetooth audio appears to be playing on the CID screen, but no sound is heard from the
vehicle speakers.
If the ignition is cycled quickly (rapid IGN-OFF/ON) shortly after IGN-ON, the previously used audio source may not automatically resume playback. (Playback can be
restored by switching the audio source.)
When selecting a track from the list within the currently playing playlist the track list
display may disappear. (iPhone iOS 16.4 or later).
After switching from CarPlay audio source to the radio source following conditions
might be encountered:
1. No audio output and volume control is inoperative.
2. If Siri was being used while listening to audio at the previous IGN-OFF, the audio
source may not automatically return to the previous source at the next IGN-ON.
3. If a hands-free call was active at the previous IGN-OFF, FM radio may play at the
next IGN-ON. (Items 2 and 3 are cases where the switch occurs automatically due to
IGN-OFF/ON.)
CarPlay may disconnect when ending Siri or ending a phone call. After this occurs,
CarPlay may not reconnect.
Correct an issue where the user name registered in the DMS (Driver Monitoring
System) may disappear.
During a CCU software update via FOTA (Firmware Over-The-Air), if the engine is
turned OFF at a specific timing near completion, the updated software may rarely become corrupted, causing the CCU to fail to boot (CID screen does not start).
Correct an issue where the user name registered in the DMS (Driver Monitoring System) may disappear.

the navigation destination is abnormal.
When the distance is greater than 1.0, the decimal point is rounded down.
When the distance is less than 1.0, the value becomes 0.1.
When the clock was set to "AUTO," the date and time are shifted to a date approximately 20 years in the future due to anomalous values received from GPS or other reasons. If
it occurs, the date and time cannot be corrected manually and have to be reset by disconnecting the battery terminal. As a countermeasure, a setting screen to manually adjust
the clock display in the "AUTO" setting is to be added to the Dealership Mode (Dealership Mode->Settings->GNSS Data Setting).
