yes you can get mulitple inputs in factory system. I have both a dvd player and Ipod playing through the UM-8....also you need a filter for the whining, again a simple thing, that will make a world of difference. A word of advice, go back and tell them to change from FM modulator...the sound quality will never be what you want it to be. For what you probablypaid they should have done the input....can't wait to see install pics
