Hello, I have a Pioneer AVH-X491BHS Head Unit. My car is a 2013 GMC Terrain. I just got done installing the new head unit and I noticed I lost some features. On my stock head unit I was able to see what fan speed on my AC/HEAT and which vents the AC/HEAT was coming out of. I cannot do that on my new Pioneer Head unit. Is there something I need to add or do to get it to display that information?
