How do I stop the incoming phone text message notifications that show on the nav screen on my 2015 Grand Touring?

The "download now or download later" (or whatever it says...) makes me crazy. I know it's irrational... but it drives me insane!

Other than placing the system in "do not disturb" mode I can't figure this out.

I do want to accept incoming phone calls... but I don't want anything to do with phone texts while I drive. I simply get too many, and they are distracting.

How can I (please!) either set to "download all, and never ask me again"

or... "download never, and never ask me again"

The most important part is "... never ask me again"

I think I've tried all the settings in my phone I can think of. I can't make it stop.

I tried in the blue tooth settings of my android phone to disable the messages option in the pairing settings - but the popup still comes up on screen.

Help!

Thanks!
