EDIT: Thanks to a helpful email, I’ve been informed that the dock does include a 3.5mm jack on the dock itself – this definitely makes a difference. Noted within the article as well. In addition, we should be getting more details in the coming days – we’ll keep you updated.
Incipio’s new auto-dock mod for the Moto Z seems kinda interesting at first glance; it utilizes the magnetic connection integrated into the back of the Moto Z, rather than other similar docks that make you stick a magnetic pad to the back of your phone (or inside your case), and it touts the fact that it’s “fully compatible” with charging, Bluetooth and audio jacks.

But when you actually look at the device, you’ll see that it’s little more than a standard vent-dock with a Moto Mod compatible cover attached via ball-joint. That being said, there is a 3.5mm jack on the dock itself, so cars without Bluetooth will have an easier time hooking up to audio using the dock.
At a whoppin’ $64.99, the Incipio Auto-Dock is probably not worth your money – but you can get to the Incipio store to buy it (when it comes out) by clicking that link, if you feel so compelled.
