Toyota Touch-n-go updates

Thanks, but I finally got an answer back from Toyota. Their touch-n-go sat nav only works with microsoft ! No plans to change, pity. The VM option to put a windows partition onto my hard drive also is a dead end, since Bootcamp doesn't read from or write to APFS formatted volumes, but is compatible with High Sierra. Apple has not updated Bootcamp or the new system APFS . Seems I have just got to wait or borrow someone's windows computer !

Thank you. In the past I have accessed the Toyota site (Safari etc)

from a Microsoft based computer then been able to download the update to

usb . Unfortunately this seems impossible with connectivity if you just

have an Apple (any sort) See earlier issue raised below on this and no

answer. The only alternative seems to be expensive , namely to

purchase VM fusion and get a microsoft partition then use that .I

wondered if anyone else with same issue had found a way round this issue
