I found a nice little app called nav launcher. All it does is provide a shortcut to google navigation. When you open the app you're taken to a screen that allows you to either type in the address, use voice, use a location from your history, or a favorite location. Once you pick your destination, you click navigate and it runs google nav. I had been looking for a way to just have a shortcut to google nav without having to go through google maps menus, and this does the job quite nicely. Plus its a very small app too which I like, since it doesnt really need to do much. I think its worth checking out. Heres the QR code
