2005 IS300 stereo head unit replaced GPS not working in Lexus IS200 / Lexus IS300 / Toyota Altezza Club Posted February 9, 2018 Just replaced factory head unit with an aftermarket one. Bypassed amp but now the factory GPS will power on with Lexus and then go black. Screen tilt works but no maps. If I plug back in the factory head unit GPS works again. Any help please?
