2025 Toyota Sequoia – Wireless CarPlay Connection Error with My Phone Only

[sdk44]

I recently bought a 2025 Toyota Sequoia and can’t get Wireless CarPlay to connect with my iPhone.

Here’s what’s happening:

•I get a “connection error” every time I try to use Wireless CarPlay.

• CarPlay works if I plug in with a data cable.
• My wife’s iPhone connects wirelessly to the Sequoia with no problem.
• My iPhone works fine with Wireless CarPlay in other vehicles.
• Bluetooth connects for phone calls and media—just not CarPlay.
• I’ve tried “forget device” on both my phone and the Sequoia, reset network settings, and restarted everything.
• Toyota service couldn’t figure it out.

Has anyone experienced something similar? Could this be a software/firmware issue with my phone or the Sequoia’s head unit?











If you want, I can also tweak this for a more technical crowd so it encourages people to suggest troubleshooting steps rather than general advice. Would you like me to make that version?

Sounds like a software/firmware issue. Try reloading or get the dealer to do it. OR, use the cable. I have an aftermarket unit that requires a cable. I ran the cable to the phone holder, and it's available when and if I need it, which is zero percent of the time. If I'm not using Sirius radio, I'm using my USB hard drive. Good luck.

Who pays for the bill on the iPhone? Phone company took over. Not the tech guys, but the bills they go with. This sucks, but it is so.
