It’s worth double-checking that the R0F62-AU000 is compatible with your Carnival’s trim level. Installation typically involves connecting the mirror to the existing wiring harness, but not all models may have the pre-installed connector. Some owners say they’ve received diagrams with their purchase, but if not, a quick call to the parts department at Kia could get you sorted. If you can’t track down the manual, some dealerships or Kia accessory retailers might be able to send you a PDF version. It’s a great upgrade, and once installed, it adds a lot of convenience!
