Tried a search but nothing specific popped up. I upgraded my phone to a note 5 from a galaxy 4. I did not consider that they would take a option like mhl away. I only use the appradio with dash command and occasionally navigation since I go a lot of places where cell signal does not exist. What are my options to be able to use those features wirelessly? Chromecast?

Miracast with the screenbeam Mini 2.

Samsung phones are very fussy about which miracast dongles they will work with. Chromecast is more complicated as you have to set a hotspot up on your phone and have an internet connection whenever you start it up.
