Hands free Car Dock app topic

I would like to have my Galaxy Note 4 hands free. That is, be able to answer calls and be able to skip songs that are playing on my Pandora player.

The stock car mode doesn't permit users to change the icons, as far as I know, and Pandora isn't an option.

What are other good options? Currently, I use CarHome Ultra, but that requires touching, therefore isn't hands-free.
