Found and ordered the Kicker upgrade kit for the standard stereo. List price for this is about $1200, most sellers discount it to about $950 and I found it on amazon.com for $549. There are four left.
I have no connection to the seller, just trying to pass along a smoking deal.
This may not be the ultimate bestest system you could put together yourself, but it comes from Ford, is fully plug and play, and 100% compatible with your existing system, which means not loss of functions in your display or steering wheel buttons etc.
Should arrive Christmas eve. I'll install it right away and document my experience.
