Can I build a microUSB cable for a Nexus 4 to get audio out and charging capability? I'm trying to break away from my iPhone 4, but I do enjoy being able to use it as my music and GPS device using one cable in the car, plus charge it at the same time. I've scoured Google and several forums, and only found that people do this with Samsung phones, and wanted to know if it's applicable to all Android phones or not. Please, no BlueTooth-related suggestions; just looking for a definitive yes/no answer. Thanks in advance!
