My fellow maxima owners,
Has anyone else been so bold as to attempt to rig the newer style 2019+ head unit in the 2016-2018 maxima? Its a lot of remapping wires so far, found a harness from china, the whole shebang.... but i have no volume control or general communication to the Bose amp despite diagnostics showing green. I also have an issue where the camera settings have no manual configuration to determine no cam, single mode, or AVM camera. And the unit is assuming its a single view backup camera and will blip to the all around cam for a half second.. Very strange.

Has anyone successfully achieved this particular victory or have advice?
