The fact that it was five door made it easier with access. The rest of the car didn't play ball. The trims were very hard to remove and even harder to replace. There were issues with the wiring. Once everything was fitted, the camera wouldn't work. This turned out to be an RNS-510 issue and the firmware was problematic (it was originally 1100, I had upgraded to 1200. Apparently, the camera is fine with 1100 and 2680 but 1200 had issues), so the firmware was upgraded to 2680 (and then the maps had to be done). There were further issues with the camera.
All in all, a 3-hour job turned into a 5-hour saga.
