I also have BlueLink version 1.5.9 but I don't see an option for 3D display. Neither do I see set up my car menu.
Just to add my Kona was only delivered on the 5th Jan this year so could be set up slightly different to yours.
Well just my luck. I am the only Kona driver that has the options in Bluelink. Just to clarify If I open Bluelink app then go to map view then the three lines at the top left. I have the following options.
My account. Vehicle report. EV service. Settings. Set up my car. Inbox and lastly Help.
Under Set up my car. The options are
Vehicle data management. Photo view/change. Change vehicle settings.
Vehicle data management enable you to back up settings to/from the car.
Photo view change enable me to add any photo I like to my profile on the head screen. Instead of the stupid inbuilt pictures.
Change vehicle settings does what it says and changes the vehicles settings. Phone connection-date time settings-general settings-sound settings-display settings-voice recognition settings-navigation settings and bluetooth settings.
Oh and something else I have found out. When in the car and I press media button. I now have an in built selection of new visual effects to watch on my screen.
I camped in the car the other night and it was in utility mode and I chose to have the log fire displayed, it really warmed me up but the crackling of the fire is irritating.
