2005 gmc envoy_slt_xl
Hey guys I'm pretty new here but had a quick question. I got a 2005 GMC Envoy XL SLT Elite but the stereo does not come with a Audio In. I was wondering if I would need to replace the whole deck with a new one? Or can i do it manually? If I need to replace it I would get a touch screen with dvd/nav but would it work with my steering wheel functions (such as volume up/down seek etc.?
