Looking for fiber optic interface to retain speakers

I'm looking to upgrade my sound / nav system on my 2011 E350 (W212) with built in nav, harman kardon speakers, etc.
My rationale for upgrading is that I am having increasing and chronic problems with bluetooth on the latest iphone and I don't see it getting any better.
Also, I would like to add airplay to my car.
No issues with the sound quality or level of current speakers but just can't live with the choppy audio anymore.

Has anyone had success with this interface? Can you recommend which product you used to integrate with existing amp / speakers and/or steering wheel?
I've done a lot of googling and looking through this forum and have found a lot of options but many of them say they don't work with the W212 audio setup.

Due to the extensive integration of the entertainment system, I don't see many options. I think the best so far is the 10" Android screen system, which also will give you the Apple CarPlay function. There is a huge thread about it. Or you could just dump the stupid Apple phone. No problems with any Andorid I've ever connected. I've also seen similar complaints about Apple Bluetooth connection dropping on the Murano forums, my wife's car.

Ironically, my last car was a Murano.

I agree with jonUF02. My Galaxy S8 doesn't have any BT problems with the NTG4 that my iPhone 8 does, but if you want Carplay you need the V2 (2GB glossy) or V3 (4GB anti-glare) 10.25" screen which is based on Android 6 with some 8.1 mixed in (including limited split view support). It can accept a USB adapter box for Carplay. Since I upgraded my Version 2 10.25 screen to software version 35 and 36 over the past 2 weeks, I have had carplay problems with choppy audio when trying to use maps like Waze with my "Autobox" brand adapter. There are other 'recommended' adapters that are probably better supported.

Unfortunately, Android Auto on the 10.25 just plain sucks because of how Google half-asses scaling. It can also run play store apps including Waze, Sirius XM, Apple Music, Google Play music, etc right off the unit, but with the scaling issue, 1280x480 makes most play store apps throw up on themselves with modal windows running off screen, buttons and graphics that are too large, etc. Carplay, when it works, looks INFINITELY better in the ultra-wide aspect of the 10.25 screen. Nothing gets squished or runs off screen.

I will mess with my V2 10.25 unit for about another week before rolling back to pre V35 software when carplay worked pretty well but the OS itself was a bit buggy. Android is still 1/2 baked.
