RNS315 currently cannot be upgraded to support CarPlay through software flashing; an additional module must be installed. Below is an introduction to CarPlay: In-car system: CarPlay is an in-car system released by Apple, which seamlessly integrates with the car's dashboard system through the official iOS 7.1 system. CarPlay does not run iOS or iOS applications; instead, it serves as a bridge between iPhone applications and the car's digital system, making it easier to control devices. How it works: The system operates by connecting the iPhone to the car via USB, initiating an immediate handshake. Users can then access various iPhone functions without needing to touch or look at the phone screen, allowing them to focus their attention and gaze on the road. This control method enhances driving safety and convenience.

I've personally disassembled the RNS315 head unit, which runs on outdated hardware with insufficient processor and memory to support CarPlay operation. Trying to flash software is virtually impossible—it's like making an old Nokia run Android. Some have attempted adding external modules, but this causes delays in the rearview camera and malfunctioning steering wheel buttons. The most reliable solution is replacing it with an MIB unit. I helped a friend retrofit an MIB2.5 for MQB platform cars, costing around 2,000 RMB while retaining the original radar and multifunction steering wheel. Don't rush to discard the old unit—you can still sell it for over 300 RMB on Xianyu to recoup costs.
