Hi team still sorting out my 93 S4 avant. Radios this time.... I can choose between a Casablanca CM62 or a Barcelona RCM 83 I want to control a 10 stack Alpine CD changer from it. Is either preferable for any particular reason??? Sam Clarkson Edge to Edge P.O. Box 27 National Park 2653 Ph 0800 800 SKI (754) http://www.edgetoedge.co.nz
