There are 2 ways to update the automobile. The first way is over the Selected Wifi Networks. The owner is recommended to not select tiered Wifi connections as updates can be gigabytes in capacity. The second option is the use of either an SD card reader, or a USB4 thumb drive. The owner will download the file to the appropriate device, and then plug it into the automobile. After that, they will select Settings > Updates > and either SD Card, or USB.
Keep in mind that every car manufactured these days are like computers on wheels. FSP Autos will be no different. With that in mind, updates are important for bug fixes, and performance enhancements. The OS will be installed on the 2TB 2230 NVME which is not user accessible, and media files will install on the up to 8TB 2280 NVME. The OS as a whole shouldn’t take up more than 128GB of data.
