Hi, I have a Columbus head unit in a 2017 Octavia vRS. My iPhone 7 is paired up with Bluetooth. When i start the car i wait for Bluetooth to connect, then plug in usb to charge. The music starts if i hit play after connecting bluetooth but stops when i connect usb. I have to restart it and lose the phone functions. Is there any way to have usb only charge the phone and not take over the whole connection?

How about using an adaptor in the 12V socket (cigarette lighter) ?

 

Like one of these :

builtin 5v/500mA USB sockets can't charge phone if it is in use

 

i use Qualcomm Quick Charge 3.0 35W with three USB sockets:

1. 5v 1A

2. 5v 2A

3. 5v/9v/12v QC3.0

and then can choose socket by necessity

 

The phone charges fine, the problem is that Columbus sees the USB device and uses that for music instead of the Bluetooth which connected first. I don't want to plug in 12v chargers in a brand new car which has a USB port.

You could either find a 'charge only' cable or use one of the many adapter that sit between the headunit and iphone cable.

 

Just as examples:

I have never used either but both should avoid the iphone attempting to sync but allowing it to charge

I use a charge only USB lead from the built-in USB socket and the phone both charges and connects via Bluetooth without problem.

Hmm i have a nice coiled mfa cable that i like but ill have a look for others, thanks. There is no software option or VCDS adaptation to disble USB data?

I think the answer will be a re-sounding no, but can the car cope with having two phones blue-toothed to it at the same time?  i.e. would it accept calls from both?

You can set the usb connecting option as 'charge only', then it won't affect the phone's other connection. Hope it helps.

How? I see no such option in my Columbus.

I think you have to do it on the phone. I don't know how to do it on an iPhone but on my Galaxy Note 4 it's in the settings

Why not play music via Apple Carplay?
