It’s the built in nav system. I’ve gone through the menu system with the owner’s manual in my hand...no luck so far.
I think there was an option to turn off notifications during the initial setup but I haven’t been able to get back to the initial setup screens. I tried doing a factory reset but it didn’t get me back to the initial setup.
I’m thinking there must be some setting accessible through FORScan which will block the pop-ups. Maybe it’s wishful thinking.
