A couple of questions, does the 2.0 upgrade take care of all the limitations in my GPS like diming the screen while driving and being able to dial a # from the phone screen while driving, or entering directions while driving?

Had My system install by Car Toys and don't know how to remove the unit to make the wiring changes needed to bypass these limites I have a f350 Ford. Any help would be great

No, a search of the site will reveal the bypass instructions though.

like diming the screen while driving

this is controlled via the illumination wire; the rest is done via the hardware bypass

go to a ford forum to figure out how to take out the dash i gauretee its prob. only 1-2 screws and pulling the rest of it out, really easy
