Hello, I like to have Wireless Apple CarPlay in my Accord, and I don't like chineese usb dongles. So I investigated part numbers of car radio receiver, check connectors and so on.
2021 Accord EX-L, after facelift comes with wireless functionality. Part number is 39540-TVA-AD1.
EX-L with installed navigation or Touring models have part number 39540-TVA-AF1.
I was lucky, and bought 39540-TVA-AD1 on eBay for just $299, from some crashed car. It just arrived, I have to install it and will see, what happens.
From what I know, this can be only possible on EX-L and Touring trims, because back side of unit have different connectors that on lower trim levels.
UPDATE:
