iPod integration does not work on iOS 18.3.2 with MFI USB-C to Lightning Adapter MUQX3AM/A

iPod Controls lost via Lightning (female) to USB-C adapters

So I have a Sony SACD Car Stereo (MEX-DV2000) that has the Unilink hub system with the Sony XA-120IP iPod Interface Adapter. This unit uses a 30-pin adapter, which you must convert to Lightning with a MFI Certified adapter from Apple themselves for a more modern iPhone to be able to have its iPod seek, and next-track & pause functions to work with the Sony head unit’s buttons. Obviously audio is sent with non-adjustable volume to the Sony head unit’s 24-bit DAC for playback; therefore you get uncompressed audio signal vs lossy Bluetooth adapter options out there people keep recommending.

There is a catch to this for charging in that you must use an inline 30-pin Scosche passPORT IFWA USB charging adapter to get the Sony to charge the iPhone.

ALL THIS CAME TO A HALT WITH iPHONES 15 & 16 with USB-C. The Apple certified MFI USB-C (MUQX3AM/A) to Lightning Adapter allows you to connect your newest iPhone (16 Pro MAX in this case), however I also get the dreaded “Accessory Not Supported” error too.

I’ve already done the green toggle switch for “ACCESSORIES” under the FaceID and Passcode Settings. No luck.

Here’s a video of my iPhone SE2 working fine with the MFI 30-pin to Lightning adapter. But the added Apple MFI USB-C (MUQX3AM/A) to Lightning Adapter does not work.

When will this get fixed with an iOS update, as iOS 18.3.2 DID NOT FIX IT?
