The infotainment system reboots many times upon startup and I'm told by the dealer the SD card needs to be updated. They want an exorbitant amount to do this - something around $600. Has anyone found a way to get this done for a reasonsable cost? I believe that software developers need to be paid for their efforts, but $600 is ridiculous. There are SD cards I can buy online, but I am aware they are not one size fits all, and have been told if I load the wrong card I can brick the unit. Any advice will be greatly appreciated.
