I unfortunately updated my maps using the KIA software. A pity the software was not tested properly. I have the dreaded problem with the speed limit system not working properly. However, my wife found a sort of fix on one of the chat forums. I pass this on for anyone with the same problem which may help until KIA sort out their rubbish software.
The problem is that if you attempt to display the speed limits on the dash display and the sat nav screen the software falls over. All you need to do is disable the dash speed limit display by unticking the appropriate box on driver assist menu and hey presto the speed limits works OK on the sat nav screen. I will look forward to KIA's total fix. Just to confirm the software update that I installed was UM_19MY.EU.SOP.012.18.211029.STD_M.
Good Luck
