I want to have a Kenwood DDX516 flatpanel touch screen to my 03 Element. I went to car toys and cost for the unit is $519. Installation is $375 plus parts. This is outrageous. Are there other units that can give me the features of the Kenwood yet not have the install cost?http://us.kenworld.kenwoodusa.com/Car_Entertainment/Mobile_Video_n_Navigation/Mobile_Video/DDX516
