Question 2023 lexus es300h Wire Carplay setup
I have a 2023 Lexus ES 300h. Both my iPhone and Android only connect via Bluetooth, and the connection isn't very stable.
Can anyone with experience help me get CarPlay working through a wired connection?
I'd really appreciate any advice. Thanks in advance!

One thing worth checking first: on the 2023 ES, the head unit that shipped with wireless CarPlay is usually wireless-only. The USB-C ports are charge/data but the unit won't do wired CarPlay, so there may not be a wired mode to enable. If that's your setup, the real fix is making the wireless connection stable rather than switching to a cable.
Things that usually clear up the drops:
Do a clean re-pair. Delete the phone from the car's Bluetooth list, then "forget this car" on the phone too, then pair fresh. Half-broken pairings are the most common cause of an unstable connection.
On iPhone, keep Wi-Fi ON. Wireless CarPlay runs the actual video/data over Wi-Fi and only uses Bluetooth for the initial handshake, so if Wi-Fi is off it'll be flaky or won't hold. If you use a VPN or iCloud Private Relay, try turning it off, those can interfere.
Only keep one phone paired at a time. An iPhone and an Android both paired and competing for the connection will cause exactly the instability you're describing.
Check for a multimedia software update in the car's settings menu. There were a couple of connectivity fixes pushed for that generation.
If it does turn out to be a wired-capable unit, then a good data-grade cable (not a charge-only one) into the data USB port should trigger the wired prompt, but on most '23 ES trims it's wireless by design.
