Google "Navigate to [location]" and Waze integration

I have been a long time Android user. One very minor but still annoying thing that I can't get to work is having Waze open up and navigate whenever I say "Navigate to [location]". I have cleared Maps as default app but what I am seeing is whenever I say that command, it opens Chrome, looks for the location, and launches Google Maps (as I think it uses a Google Maps link on the Chrome search results).

Any workaround for this?

How to keep FM Radio playing on background with Waze running

I have a 4.4.2 Caska Android HU.

Everytime I open Waze or Google Maps, FM Radio stops playing in the background.
But if the song is coming from Spotify or TuneIn, it keeps playing in the background.

Any solutions for that?
