I did a lot of research tonight... and I finally know what to do with my stock Navi. I need to purchase a Navtool and a mirrorcast wifi device. I may have to put my headlight on hold until I sell my Zele carbon fiber front lip (extra). So the Navtool will allow me to use my backup cam (automatically comes on when it is in reverse) without partially having my ebrake on, pressing the aux button, and the mirrorcast will allow a mirror image of my smart phone. Here's an example on youtube
