Topic: Ford factory radio interchange
So one of my teammates invested in a new tow vehicle, an '03 E250 cargo van, and it has the most basic of radios. Said radio also has a busted volume knob so the thought is to upgrade to another Ford radio with a CD player. This stock unit has a spot for only one plug from the harness since the van only has 2 or 4 speakers. A number of other Ford radios that will accept the plug in the van also have another spot for a second plug. I'm assuming this is for additional speakers and possibly steering wheel controls? I don't want to drop $25 at PnP to conduct a radio experiment so can anyone tell me if another factory radio will work?
