The company www.mapnsoft.com
is what is running on your GPS. They have map updates for $145 if you download it to your current SD card. I would ask them if AA will work on their system. They run the software and provide updates to the software (AA and Bluetooth) that talks to the phone.
Plus the problem, Hyundai went on a renaming spree ! The Santa Fe Sport is now just Santa Fe, you have the XL, which use to be Santa Fe and whatever new model they just came out with. I my wife says her 2014 Sports could not do Car Play .
No, there are no hacks. The SD card means Secure Digital. As to date, no one had broken the code to the hidden area on these disks. And any downloaded update requires a VIN so it can only be used on that car. Other form users have tried swapping to a newer Hyundai GPS model and get funky results or blank screens.
The dealers are clueless, really clueless... unless there is a part number, they have no idea nor care. I believe some owner have swapped out the GPS for a different brand... but look at many hundreds for the part, installation and adapters so your steering wheel buttons will work.
Hyundai has to be better then Ford's Sync system where a company is selling entire SYNC backs (CPU part) from accident cars to rid owner from the horrible SYNC 2.0 system that was outdated at $1,500 for just the part. Want a GPS CPU, add another $500 !
