Parts & Accessories Monitor Converting a Honda Accord screen to CarPlay. The most important thing is that you have a double-knob stereo, not a single-knob. It converts the information screen to CarPlay while keeping the original Honda system. I bought it for 1700, and it turned out not to work with my model because my stereo has a single knob. It must have a double-knob stereo like the one in the pictures, and I haven't even opened the box. Bidding starts from 600. I need to sell it urgently. May God grant us all success. 🙏
