So the infamous 12.3” finally made its way the the Big horn, if you’re like me and already had the Big horn then this sucks. I’m wondering if you could get this added seeing as it can be build with the option now. The dealership seem clueless they didn’t even know big horn had it as a option when I asked. One guy told me he would find out called me back and said it’s impossible because of my speaker setup which sounds ludicrous to me. If you build one you don’t need the upgrade sound system so why would it effect me now? Has anyone made this upgrade to a bighorn they owned before the option was available?
