AMI question

Can someone enlighten me on how you connect devices to the FL A3 for music playback?

I both my pre-FL A3s, I've had the AMI interface where you need to navigate the minefield of colour-coded cables depending on what you want to connect to it. In my case I've used a dedicated iPod Touch with the correct AMI cable to provide music in the car.

What's the deal now? Does the AMI interface still exist? Does it work in the same way? What other options are there (besides bluetooth). If I physically connect my phone for CarPlay, can I then stream Apple Music or Spotify or whatever? So many questions and, as usual, the brochure is light on details.

So can I still use an iPod or is that out? I don't really have any interest in CarPlay per se and don't really want to faff about connecting my phone to a cable all the time, just using it via Bluetooth for calls as normal etc. My current setup of a dedicated iPod for tunes works well.

Ah so you can just connect the iPod Touch to the USB instead of AMI? Does it still let you navigate the contents by Artist, Genre, Track, Album and so forth?
