Trying to get this worked out with my dealer this week. They are under the assumption it checks for updates daily or every time it turns on. I try to politely tell them they must be confusing it with the traffic updates that the Sat-rad does because there is no way a GPS system will be able to varify it is due for updates via GPS only.
I printed the home page to the company above, so hopefully that will help them find a better answer. I am going to call the 1-888 number now to see what I can find out exactly since they don't even list the Forte on their site.
*****update after phone call to MnSoft and Kia:
So I called the 1-888 number for MnSoft and spoke with them and I was told a Kia Forte Nav system update will be available in 2-4 weeks at which point they will update their website to include the Kia Forte as a selectable option in their update menus.
To top things off, I just got off of the phone with Kia Consumer Affairs and got some disappointing news. It appears as though Kia does not cover the cost of any system updates, so I may have to rely on the goodness of the dealer to pay for this first update and possible future updates.
