Here's my challenge: I bought my daughter a 2020 Sentra S that does not have CarPlay installed. I went on eBay and bought a replacement stereo from a 2021 Sentra SR, and thought it would be a simple plug-and-play, but no. Although both stereos use the same 20 pin and 40 pin harnesses, the wires are configured differently. Does anyone know where I can find the pinouts for each of these model stereos so I can swap the wires around to make the new unit work? The old stereo has a 7" screen and is part number 28021-6LB0A and the new one has an 8" screen part number 2591A-6LW0A. I have photos of the wire harnesses if needed.
