Got it working, had to download a stuffit expander and get the proper files, then do a system reset on MFT. Then it let me do the update from the usb. Only took about 30 min. Ran through everything I could think of and it all works just fine.
I had a Chinese built unit in my old Mazda 3. It worked great for almost 3 yrs. Then out of no where every time I would make a left turn it would switch from NAV to DVD. Not sure if it was the unit itself or some crap wiring in the Mazda. I sold it then sold the Mazda for my edge.
I believe that piece goes in the cubby behind the ac controls. I didn't notice it until my wife said something like hey there is another cubby hole back there...just above the power outlet on the passenger side.
