  1. Can a Kenwood KOS A 300 ipod interface be added to my 2003 Dodge Ram 1500 with Infinity stereo system? I’m not sure if it has an auxillary 3.5mm input on the back of the factory radio. The radio is a am/fm cassette, single disc cd with cd changer controls. Any help would be greatly appreciated.

  2. If I’m installing a stero in a Dodge Ram 1500. Is the antenna wire that came out of the original stero suppose to fit the new one or do I need an adapter of some sort?
