The Metra 95-6528B Double-DIN Installation Kit for Ram Trucks 2006 to 2010 lets you change out the head unit for something more modern and still have a factory-looking fit and finish. All Metra kits come with the needed hardware—all you have to do is provide the tools. Metra recommends disconnecting the negative battery terminal before beginning any installation. All accessories, switches and especially air bag indicator lights must be plugged in before reconnecting the battery or cycling the ignition.
