A:Answer check out the web - most car makers listen to consumers about aftermarket parts and needs we have when we want to alter the components of our entertainment systems. I mean if they don't listen, they just want to lose a large audience to their competition. look at your consumer electronics store. my Best Buy was able to order the harnesses and after market parts from reputable sources via their in-house computer (dash adaptation façade was from Subaru). the parts were at my doorstep in 3 days. as to the difference in screen size, let me ask you - which one is less expensive?
