Swapped with a PYLE head unit since it had the AUX port that I needed (ant not a whole bunch of expensive stuff that I dont need).
It may be a little late but the Clarion XMD3 does have an aux in -- but it's on the back on the head unit. I ran a line from there up to the helm where I've got an AUX IN (single 1/8") where I normally have my SXM plugged in but I can also plug in the phone or tablet.
