iPhone 15 & Apple CarPlay
Broke down yesterday and bought a new iPhone 15. Today I wanted to connect it to CarPlay but a weird and lengthy message popped up as I plugged in the USB-C cable to the USB connector tucked in the cup holder. Wanted to go past it but only option was to accept it and CarPlay hasn’t been able to connect since … only option is Bluetooth and that is somewhat iffy at best. I want my full CarPlay screen back. What did I do wrong and how do I get it back the way it was with my old phone? I sure hope it’s possible ….

Without providing the lengthy message you agreed to, we can't read minds to know what you did. For starters, though, given that the iPhone 15 has a USB-C port and I believe your model year E63S still has a USB-A connector, the first thing you need is the proper USB-A to USB-C cable that supports data and charging. The biggest problem with USB is that not every cable is the same. Some only support charging, others support data, but only slow data, others support fast data and so on. Same goes for USB-A to USB-C adapters. They may not support everything.
I haven't made the switch to a USB-C iPhone. I need to replace my iPhone XS, but I'm waiting till September when the iPhone 16 comes out. I'm in the same boat with my 2019 C63S that I will need a USB-A to USB-C cable and I found the following. Apple doesn't make one last time I checked. It's a nice short cable for the cup holder area. Ignore that the description says this cable does not fit iPhone. That's for the older lightning port iPhones. Also, this is a USB 2.0 cable, but that's all you need for CarPlay, so you can ignore the one star reviews that complain about the cable not supporting USB 3.0. This is the problem with USB cables. You have to read the specs and make sure it fits your use case.

I got this cable and obviously it’s not the right one. I’ll try what you sent me and go from there! Wish I’d have taken a pic of the screen ….

while I wait for the cable to arrive tomorrow, I played around a bit with my wife's '22 GLE350 as she got a new phone as well. Her car has an aftermarket MagSafe charger and she's got a MagSafe case for her phone (which I don't on mine), and in order for her phone to connect to CarPlay, the phone needs to be plugged in directly to cable and not just connected to the MagSafe charger. I was under the impression that on hers I should be able to just plug the cable into the MagSafe charger & the dashboard outlet and it should connect to CarPlay but it won't . . . I imagine that has something to do with the fact that as we bought the car, it was at the tail end of the severe covid restrictions in regards to parts availability etc and we were told a couple electronic elements will not be working as designed due to that . . .

I have two USB ports in the center console but I never plugged my old phone in any of those. I always thought plugging into those I'll connect to the same system . . . . But worth a try I suppose . . .

it was supposed to originally but the COVID thing changed availability dramatically so her car didn’t come with wireless CarPlay …

this cable arrived this morning and I tried it right away. Unfortunately its still not working . . . I connected my phone to my wife's newer GLE with the cable the phone came with and it works just fine. Maybe I need to try one of these and use an Apple cable?

got it to work! I was able to replicate the message and it was just a 'warning' that some info will be sent to Mercedes Benz . . . but this time I was able to just go past it (which where my mistake was made as I originally declined it) and it took me straight to CarPlay. (And I was able to do that with another cable I had). There are a couple Bluetooth connections and I tried to delete those but did not find a way to get that accomplished . . . my car never showed up on any screen originally which was one more thing that surprised me as well so I was never able to 'Forget This Car' which is one of the things I was looking for to begin with. But I think I'm all good now, thank you for walking me through this! Was frustrating to say the very least . . .

I Just took my newly Purchased used 2021 GLE450 on a shakedown roadtrip to the Martin Guitar Factory in Pennsylvania.
On this trip, using the wireless Carplay adapter after a number of hours CARPLAY starting acting up, disconnecting and screen flickering, loosing audio connection, etc.
I opened another carplay adapter, NIB, and replaced the other one. Same symptoms immediately.
I happened to have an Apple wired cable and installed that in place of the wireless adapter into the forward Carplay USB-c adapter. It felt like a tighter fit and worked for a while, but when bumped it would lose connection until repositioned.
I am convinced the USB-C Port plug is worn and failing. I called my local dealer to bring the car in while Warranty remains. The rear window washer pump doesn't work either.

Charge only cables should be required to have a proper label 
Bites me every now and then hooking up an Arduino or similar device only to find it won't communicate with the computer. After being burned the first time, that's my next check, find a known good data cable.
Problem is so many devices ship with charge only cables that they accumulate around the house and odds are high that I won't grab a data cable when I want one. Grrr.
That said, I do keep some in my laptop bag for use at airports and hotels, etc, where I might want to connect up to some unknown USB power source. Can charge with peace of mind knowing my phone's not being jacked.
