I have a Galaxy Nexus 4.2.2 which is on the compatibility list for my Pioneer AVH-P4400BH under HML. I am able to connect via Bluetooth however the USB indicates incompatible device. Pioneers website indicates HML, I do not know what this is and how to connect it.I looked it up and it looks like an HDMI connection to a Micro-USB allow I could be looking up the wrong item.
Can anyone tell be how to connect this so my other options work? Also what is HML for Android in regards to my stereo? It seems like such a waste of a stereo not using all the other functionality.
