If you upgrade the radio in your 2009 to 2013 Acura TL or TSX and want to keep the climate information available, you will need to replace the factory navigation display with a non navigation display. When you replace the display you lose the factory backup camera. If you want to retain the factory backup camera and view it on your aftermarket radio you will need this harness.
This harness provides the factory camera with the correct amount of voltage (8v) and gives you an RCA to connect to your aftermarket radio. If your factory camera has multiple angles only one angle will work with the new aftermarket radio and you will not be able to switch it. In order to automatically switch your aftermarket radio into reverse you will have to wire tap the brown wire on the 12 pin or 20 pin connector that used to plug into your factory radio. See the images for the pinout. If you are looking for the harness in the video for the android radio for the Acura MDX this is it. Here are the instructions
This is the breakdown of the connector per car
2009-13 Acura TSX 28 Pin
2009-2010 Acura TL 32 Pin
2011-2013 Acura TL 36 Pin
2011-2013 Acura MDX 28 Pin
