I can't find any reference to this. It is a tiny SD Micro-size port under the radio and CD player. Nothing in user's manual about it either. Any answers would be appreciated. New 2017 -- 200 SUV owner.

Thanks you

Are you asking what it's for?

If so, it contains the map data. So when you need a new, updated (more current) map, you buy the new SD card.

 

Thank you! It doesn't have any card inside of it. I'll check on it now that I know what it is for.

Thanks Again
Dave
