First time poster, be gentle. I have just bought a '99 Pathfinder and today I fitted a Sony head unit using the Nissan factory harness and all is not good. I only have right rear speaker and when I disconnect the aerial lead (the 2 wire one with adapter) from the head unit the unit powers down (turns off). I have fitted quite a few unit to a variety of vehicles and never had this issue before. Any help would be appreciated
