🤷 Sorry, I can only attest for the 2006 model year.

As far as I've found, no. Take good care of that TWC charger.

The MagSafe Battery Pack and the MagSafe Leather Wallet With Find My Support (both Apple) are the same size. On the 14 Plus, the onscreen indicator when connecting either is the same size as the accessory.

Can anyone with another size of 12, 13, or 14 (non Plus or Pro Max size) test and confirm. Again, Either the Wallet or Battery Pack will do. (FYI, the paperwork insert with the Leather Wallet is the same outline as the devices.)

I believe that using the "Remove" command in Find My app (Items) will reset the AirTag for another person to use. It disconnects it from the Apple ID used to register it. Have tested this.

Of course, if the AirTag is malfunctioning, this battery method should suffice to fully reset it. You will probably want to remove it from the Find My app anyway so new registration can proceed. (I have not tested performing this hard reset and then pairing with my ID while it was still registered.)

Delete the pairing in HFL (as per the manual), and pair the phone again (as per the manual).

You have a problem with the HFL system then. Troubleshoot or take to a dealer for investigation.

Ensure you don't not have the same vehicle/system that this is listed under. ;)

Yes. Check circuit breakers/fuses. See if the unit is disconnected. Ensure that the ignition is on (not ACC). Check if there is a status displayed on the MDM or touchscreen.

Also verify that the audio system speakers work (i.e. play radio, CD, AUX), since all HFL sounds are played through the audio system.

Good point, thanks. Added to the relevant step.
