Metra dash kits, at sonicelectronix.com, offers both black and silver ones. That would be the kit I would use. It's easier than finding the Nav bezel and making it work.
Go through the double dins on sonic and you'll be able to pick out the ones that come with all the options you're looking for. Personally I would stick with Pioneer, Kenwood, or Alpine. I had the DDX 512 and although it's outdated (discontinued now) the controls were nice. Can only imagine the speed and response you get from the units they have now.
Look up on YouTube the work that is involved with putting a tablet in your dash. Someone on here sorta did it but imo you're better off putting a double din in and call it good. A tablet wasn't designed to be installed into a car dash.
