CarPlay sends a H264/5 video stream from the iPhone to the car's head unit, and receives touchscreen, knob, etc. input in the other direction (afaik). I'm not sure if the video is encrypted, but it seem rather unlikely that the dongle could exfiltrate such an amount of data undetected.

I kinda just don't get wireless CarPlay/Android Auto at all. If I'm going to connect my phone to my car wirelessly for that, it's gonna drain the battery. So I'm going to plug it in so it can charge. So... now it's wired, so why do I need wireless? I guess if you have a wireless charging pad in your car, then that's a little bit more convenient. But the big inconvenience for me is just to have to take it out of my po…

I have wireless CarPlay in my car and I don't care about plugging it in for short rides. It's convenient that I don't have to plug it in every time I am on a 20-30 min ride just to get directions. It's a very useful feature. Not a deal breaker but a very good nice to have.

For quick trips where you don’t want to screw with cables, or where you don’t want to override your passenger doing the connect. I like wireless for CarPlay eve though my phone isn’t hard plugged into the head unit bit is still charging from the car. So for me a cigar lighter power plug is still better for charging the phone even though I have CarPlay wireless active

Do you feel the same way about WiFi? The big hassle is getting the laptop out of the bag, not plugging in the Ethernet cable?

Can someone recommend a dongle that actually works? I’ve tried a few and they are highly unreliable or stop working after a few months.

I've used a Sunweyer dongle from Amazon. If you can't get the "new shopper" discount on Aliexpress, it's cheaper. Seems to work fine. Doesn't like pairing to multiple phones, and the phone doesn't like being plugged into one of the car's USB outlets (it drops the audio because AFAICT the phone thinks it's plugged into the car for audio, but the car is still expecting audio over the Bluetooth "CarPlay" connection), even if it's one of the outlets that's not supposed to do anything but power.

I'd use it a little differently, but it's my wife's car, not mine. Who would have thought a 2022 Mercedes would have wired-only CarPlay?

Anyway, I find it excellent for podcast control. If maps are off (in my case, because location services are turned off) it doesn't really use more power than plain Bluetooth audio, and when I approach my destination on a trip I'll turn on location and plug it in to juice up the last bit.

The battery bit only makes sense if you enter your car once per day.
