So we took a short road trip in Aoi a few weekends ago, and I connected my phone to the factory stereo aux input, along with using a USB power adapter in the lighter socket. Ended up with alternator whine. The factory stereo in Shiroi (our 2013) doesn't do this, but when I connect the phone I use the built-in USB port for power (instead of an adapter in the lighter socket).
Anyone encounter this with their 2, and have a good solution other than buying one of those noise-isolating cables (that also make the sound terrible)?
