The battery in my 2022 MDX Aspec needs to be replaced, but no radio or navigation code stickers or cards are available. I accessed the Acura dealership diagnostic screens on the display to get the serial numbers. Only one serial number was shown. Using the Acura My Garage website, I was able to get the same code when I entered the serial number in the radio and the navigation fields. My question for those of you that have code stickers or code cards, is there only one serial number and one code for both the radio and navigation? Seems logical, but I would like to confirm before removing the old battery.

 

Turns out that no codes were needed when I replaced the battery. All the error messages cleared up without any problems. Only remaining issue is inaccurate fuel range number. Based on past experience it will gradually adjust after the next couple of fill ups.
