iPhone 18 Pro Max not connecting to CarPlay. Does not recognize USB connection.

I purchased an iPhone 18 Pro Max 2 days ago and I'm having trouble connecting it to my 2021 Toyota Corolla Hybrid (which has a USB-A port). CarPlay doesn't automatically launch when I plug in my phone via USB. The phone charges, but CarPlay won't connect and the car doesn't recognize the USB connection. I've already tried resetting network settings on my iPhone, resetting all settings in my car, and using a genuine Apple USB cable, but it still won't work. This is honestly so frustrating.

Re: "iPhone 18 Pro Max not connecting to CarPlay. Does not recognize USB connection".

Seems ensuring the firmware in the stereo / infotainment system in the vehicle,

(ie: Check the vehicles manual. or the manufacturer's support website, for info.)

and the iOS version on the iPhone (check in Settings > General > Software Updates)

are both up-to-date with the latest versions can often avoid issues.

Hello dazzlefrost,

In addition to brbo's comments, try a different cable.

Recent CarPlay implementations, are fussy about having the correct cable with both charging and data capabilities. Go online and look for a recent name-brand one that specifically mentions CarPlay.

Good luck.

EDIT: I had to buy a third-party Aluratek wireless adapter for $80 for my CarPlay to work. It's frustrating that this iPhone 18 at this price point requires an additional paid accessory for standard functionality. Please address this.

I have tried different brands including Apple products. Still the same.
