What this means is that if you can connect a device that has an Auxiliary output, such as your iPhone/iPod, smartphone and MP3 players straight into the Auxiliary input of your head unit. So basically a cable that has (2) 3.5mm audio (male) plugs. IMPORTANT: Please beware that this feature is not the same as the “Full iPod Control”. This feature will only allow you to control your music by clicking on the designated buttons via the face or front side of your unit.
