I can't use another company's GPS system in my car, so in the market of, "Using GPS navigation / menus / etc in my 10 year old Mini's dashboard" there's no meaningful competitor. They charge for map updates and everything.
At some point a company is just building a feature, and they're not required to make every single feature accomodate every other manufacturer's competing version of the feature. I knew I was buying the Mini system when I bought the car, and I accepted it. Same is true for iPhone users.
