Step 1: does your car have wired CarPlay or Android Auto?
Plug your phone into the car's USB port with a cable. If the CarPlay or Android Auto screen appears, the car is a good candidate.
Step 2: which USB port?
Use the same port that carries CarPlay. Some cars have several USB ports and only one handles data.
Step 3: check the seller's list
Reputable listings name supported makes and models. If yours is missing, message the seller and ask before ordering.
Wireless-only and aftermarket stereos
Cars with wireless-only CarPlay and some aftermarket stereos can be hit and miss. Ask the seller and check the return window. Then browse the best sellers.
