Review on PAC RP4 2 HY11 Replacement Interface Pre Programmed by Jerry King

Very few complaints as this harness/adapter box was fairly easy to connect to the head unit rail with the rail provided (I used it with a Pioneer DMH-1500NEX which it works CarPlay/Android Auto, just for reference). Likewise, it actually retains steering wheel control, as well as parking brake detection (the latter doesn't need to be wired directly to the parking brake switch, which is nice), and even gives cues from the headlights to be automatically dimmed/on at night. Head unit touch screen mode when using Android Auto. However, the only thing it can't do (at least in my 2014 Hyundai Accent) is transfer data via the USB port (although charging/powering works). This seems like a small thing, but since my main unit only works with Android Auto via USB, it's a problem. In the end I was able to route a Pioneer USB cable and epoxy mount it in place of the factory USB connector, but this was a real problem and I suspect many just unplug the USB cable from the main unit be where they can (probably a glove). box that is far from perfect). Since much cheaper harnesses (like the Metra version) can do basic pin mapping for stock head unit connectors, that's definitely a premium compared to this $100 harness. To be fair, I suspect the USB connectivity issue has a lot to do with the factory wiring/data transfer capability of the standard USB port itself, but Radiopro shouldn't advertise compatibility, which they can't guarantee. However, if you want SWC and rear camera options in addition to plug-and-play connectivity to standard Hyundai head unit sockets, then this is the only game in town.
