Anyone installed an aftermarket headunit and retained the steering wheel bluetooth controls in the 2013 civics? I'm getting the Pioneer AVH-P4400BH and would like to use the BT controls on the steering wheel, the closest I've found to doing this is using 2 PAC units as seen here: http://www.pac-audio.com/SWI/SWIApp...u=Pioneer&swiOptions=Radio with or without BT
