You don’t need one. It’s just a car mount with wireless charging so you can just slap your phone on it and go. If you have a different amount, you might have to plug in your phone so an additional step. If you’re using the Pro Max and you have a bumpy car it’s possible your phone might not stay attached over rough roads.Can someone explain why I need a MagSafe car mount?
Ideally, what you want is a car with GPS or CarPlay so you can use navigation without having to look at a relatively small phone screen. That is the way to go.
If you’re someone that never uses GPS then you probably don’t even need a phone mount.
