You've never been to death valley without air conditioning Or Russia without heat. I think the infotainment system in this case has a broken climate control function. There are workarounds, but why if you don't have your phone?
Also, since many of these places have a lot of used cars that once were in the EU or other places with legally required computers, this is changing as now most of the mechanics even in relatively poor remote places have to have these devices as now many of their local customers don't have "computerless" cars any more, and the existing pre-2003 cars won't last forever even there.
