Maps plus and unlimited data

[Beefrob]

Why are all of the apps available with the unlimited data plan except maps plus?  If I have to use maps on Android auto, then there is no good reason to pay for the plan.  I can just use the Android auto apps and use the data connection from my phone.  Frustrating that the cheaper plan without data includes maps plus but the data plan leaves that one app out.  Sorry rant is now over.
