Coming from another phone that has a 3.5mm jack and miniUSB jack side by side, I made a cable for my Honda Element that takes both cables neatly from my phone (left side) back to the spot on my Element that has an AUX port and a charging port with in close proximity to each other. (right side)
It is there for easy to grab the phone off my cradle, unplug and talk, or leave the miniUSB in and talk.
My question is with the 3.5mm jack on the top of the evo, it is going to be a royal pain to unplug while driving if I get a call or to even rig the thing up at a stoplight.
Can audio be accessed from either the microUSB or the HDMI on the bottom of the device to send to my stereo for listening to music or pandora?
