Mystery Murano...No RADIO, No HVAC, No fun!

Owner of this 2009 Nissan Murano tried the "eBay parts cannon" to get his HVAC and Radio back online, but failed. He then towed it 4 hours to PHAD for a diagnosis. Let s see why the Radio, MultiFunction Switch, HVAC, and Rearview Camera are all offline... The diagnosis gets more interesting in search of the ROOT CAUSE of the failure.
