Does anyone know if a usb hub will work to allow connection to apple CarPlay and power a secondary device?? I am wanting to use a WiFi dongle but because the 12v supplies are permanent live, I want to use usb to power it...

A similar question was asked a long time ago so I tried it. It won’t work.

An unpowered hub will only support, recognise and power one connected device, so it’s pretty pointless using an unpowered hub as it behaves solely as a single-device pass-through.

I’m not aware of any 12v powered USB hubs and I doubt the USB in the car would recognise more than one attached device and in any event you’d need to wire such a hub into an ignition switched 12v source to achieve what you want.

Ah well, thanks anyway  

Would anyone know if there are unused USB's at the back of the headunit or elsewhere that could be tapped?

I would think it possible to fit a 'power on at ignition' usb port maybe in the arm rest compartment but I don't know how you would get a data connection.?

I use 12 volt step up transformer from Belkin in the rear cig lighter socket, it provides a mains power socket (for a Surface tablet) and two powered usb's leaving the front usb free.
