Steering Wheel Bluetooth Controls

I am looking for a steering wheel mountable, Bluetooth controller for an Android device. Currently, I am use a device called Bluclik. It works great for audio control. I can control volume and change tracks in all audio apps. However, I am trying to get full navigation control. I'd like at the very least, to have buttons for up, down, left right, enter/select and volume. If something also had back, home, and overview buttons it would be perfect.

I have been searching for a few hours now and have failed miserably. So this means either what I want doesn't exist or I have failed to internet good enough. Any help will be appreciated, thanks.
