I couldn't believe that it didn't wait for user input before starting the update. I also second the "please remove thumbdrive" text...
It is funny you mention KiaConnect and OTA data. My wife recently got a Mustang Mach E; all of her updates are pushed OTA. Hell, her
Apple Carplay and
Android Auto are over bluetooth, not wired.
Granted, neither of those are a big deal, and even the update running twice in the end wasn't *that* big of a deal; just annoying--and not as annoying as getting e-mails from the stealership group that sold me my car saying, "Now is a great time to buy a Kia!" Yesterday. I've barely had my car two weeks. Can't I just enjoy the one I just bought?
Sorry...I digress. But yeah, I'd think if you have about an hour with nothing better to do then maybe you grab a book and update your car's maps/firmware.
