Trying,unsuccessfully, to get googlemaps dirextions to play thru car speakers. Bluetooth button as source and this came up.

Can i use this it,,if so how??

There is no online map update functionally for the Columbus/RNS-510 using bluetooth or otherwise. You'll need a map update DVD or DVD converted to SD card.

 

That appears to be output from an app on your phone at a guess. Have you watched a youtube video about map updates recently? Perhaps this one which matches both the 'artist' and 'title' from your headunit:

 

 

On a side note, I run android auto on my phone and connect via BT. As my music is streaming from my phone I also get navigation prompts through the car speakers if that helps
