Call up KIA and demand it. Keep escalating it. I unfortunately used the same USB for both updates, so the old one is totally gone and I can't download it again to try. KIA and MnSoft both say it cant be downgraded. I KNOW that is not true. If the system has writable flash memory, it can be rewritten with different software..duh. Thats how we got the new software! There very well could be logic in there to check for and reject lower version numbers, so if I had an old copy of the software maybe I wouldn't be able to use it, but you better believe that there is a way. It may be that MnSoft would have to send a special version of the software, like the old software with a version number bump or new signature...or maybe a dealer could reflash the head unit. There is a way.Thanks, any way yo reset to old version and get rid of new one?
I would prefer KIA to address some of the shortcomings to make the system better for everyone though, but I really want the old version back in the short term.
