I have been trying to update both to software 22251 and MY21 maps on my MY20 APIM. When I wouldstgart the process, it was extremely quick saying the USB is ready to be installed and uploaded (maybe less than 30 seconds). I would let the truck run for about an hour and it would not work. After a second attempt, it did the same things. So on the third try, all I did was upload the 22251 software first without maps and it took quite a bit longer (around a minute) to prep the USB drive. The software updated in the truck in 20 minutes.
Is there a reason why I’m having a hard time uploading the map software?
