I have a 2021 GMC Sierra. I tried playing music off a new Ipod on my way home and could never get the truck to 'see' my device. It recognizes my Samsung S21 but can't get the Ipod recognized any which way. Called the Customer Service number and sadly, they said they don't have a clue after reading to me what the owners manual says. I'm not a happy customer GMC in case you are following these forum conversations!
