Hello everyone. New to this section. I have a 2010 R/T AWD 90k miles and my factory radio is on its way out (REN). It keeps powering down and booting up every 5mins or so on its own. I was wondering if all I needed to upgrade to hands free is the RER radio and a new interior mirror with the microphone. My mirror is manual currently, I don't know if the harness is there for the auto mirror or not. Any input would be nice or if there is a link to somewhere were this has been done, I can't seem to find it.
