I wanted to know if someone can let me know how to remove the factory navigation radio on an 08 Mega cab.

Any help would be much appreciated, if there is a link with photos that would be fantastic.

thank you

 

I was able to pry my dash bezel out with a screwdriver. It is just held in with spring loaded tabs all around it. My 07 Quad cab had a couple screws holding the bottom on which entailed a lot more work because the whole center console had to be disassembled just to get to those screws. I have pulled the dash off of two Megacabs now and neither had the screws in the bottom...
Try prying out on the bottom of the dash bezel with a thin screwdriver but be careful not to damage the plastic dash. Once the bezel is off then you just have to unhook all the electrical connectors to finish removing the dash piece. After that it is just a couple screws holding the Nav system in place. If you plan on removing the Nav antenna then you have to pry the piece of the dash top off too that is just below the windshield. A screwdriver will help there too...
