2014-2018 Mazda 3 Skyactiv Audio & Electronics
Hi!
I have a 2015 Mazda 3. I use a GoPro as a dashcam and iPhone for navigation. Since the USB ports do not have enough power, I have to use a car charger. I have only one but I need both the iPhone and the camera to be charging.
If I plug the camera into USB hub, it charges but I cannot start...
