Default [Q] frAccess my phone from my tablet?

I'm building my new galaxy tab 7 into my truck. I am planning on hooking my tablet up via Aux input and connecting my phone via Bluetooth. I would like to be able to use an app to see my phones desktop and control calling etc through my tablet. Is there an app that allows me to do that through Bluetooth or wifi without having to root my phone or do it through a website? Ideally a widget but any app would be amazing.
