Guys I`m really serious about pulling the trigger on a Appradio 3, I have 2 questions, without using a App is there a way to add siruis xm with a adapter or external Sirius unit to the headunit? Can I mirror Google navigation? I have Xperia ZL which is listed at compatible phone and use the MHL adapter, so if does mirror Google navigation headunit  can I control everything on the head unit?
