Hi all. I have my first Mazda (coming off a Subaru) and I use my phone for navigation. In my Subaru, I would plug it in to the USB adapter that I put in the "lighter" outlet and it would prevent the battery from depleting during navigation and even charge it up. My new Mazda can't do either. I plug the sam phone with the same charger cable into the already existing USB ports and the charge is such a trickle, it only charges if the screen is off. Not really great if I'm navigating with the phone. It can't even maintain the current battery level, which would be fine with me. Anyone else have this issue, know how to fix it, or is it a repair issue?
