Replaced the uncoiled cord that comes from the front of our head units and is obsolete. This one is better because it rolls up to the same just under a foot length, but the passenger can comfortably hold the phone and queue up songs without unplugging or leaning over the head unit. It's also nice to have a 90 degree USB camera plugged in. upside down so you can slide the cable left or right. I just want it not to glow green when it's on. I'll probably cover it with duct tape or something. The whole car inside is red and there is a bright green light under my phone. Spring.
