I went with this one from Amazon.
VANMASS 2024 BEST Car Phone Holder [Upgraded Suction & Clip] Rotatable Universal Mobile Phone Mount Dashboard Windscreen Vent Cradle Van Automobile Accessories for iPhone 15 Pro Max 14 13 12 8,Red
I have it clipped to one of the air vent blades, with the clip the other way up from the Amazon picture. It seemed to fit better with the metal hook part being under the blade and hooking upwards.
There’s a few negative reviews on Amazon where people have said their vent blade got snapped, but I think you’d have to be pretty heavy handed and have maybe inadvertently knocked it to do that. It cannot be over-tightened when fitting because the tightening knob is ratcheted and it just turns and clicks when tight.
Overall I’m pleased with it, and subjectively I think the Apple Car Play navigation is less laggy with the phone in the “open” than it was when it was laying down in the cubby space below.
And it’s red to match the car!
