Same here in Toronto area. Even the latest version of the maps is woefully out-of-date compared to Google. Roads are missing. The worst aspect is the speed limit marking--missing on most smaller and rural roads and woefully out-of-date in the city where there have been recent campaigns (over the past 5+ years) to slow things down street-by-street. This major flaw would be avoided had KIA chosen to use the vehicle cameras to "read" speed signs (as Volvo and others do) instead of basing the indicator off the maps database. Before you get snooty and say KIA is not Volvo, KIA already has this technology and uses it on some existing models. It was a just choice (marketing, economics?) to not deploy it on the Stinger.
The fundamental problem is that HERE maps require users to update all this stuff and it is a relatively clumsy interface and slow turn-around time for updates. I did a few myself as a test. Assuming HERE eventually gets around to the update, then there is a delay before KIA picks it up and then there is a further delay before a KIA owner pays for (except in certain "lucky" countries who get them for free) and acquires the update.
The whole scheme is an embarrassment that suggests poor planning and comprehension of electronics, or, laziness assuming everyone will use Android or Apple anyway so why bother implementing it properly. I'd have no problem with the laziness if they were charging an appropriate optional price for the built-in nav...but instead we are paying through the teeth for an incompetent system. Even a handheld GPS would be better in several ways.
The criminal aspect of it all is the bundling of the UVO interface ("operating system") with the maps updates. All interface updates should be free and auto-update like most vehicles (even ones like Ford). The maps are a different story, but I think most people expect free maps updates when you are paying such an excessive cost for the system in the first place. You get (vastly better) Google or Bing maps updates for free while paying much less for the "system" they operate on.
