I've got about 2,500 miles on my 2011 Edge. Also had a 2010 Flex and 2010 and 2011 Taurus SHO's in the past couple of years.
The Sync/MyTouch in this Edge is a serious devolution from the "normal" Sync system, such as that on a Taurus or Flex.
Here's my take on things.
1) The Hazard switch. Seriously? In many decades of driving many cars, never have I "accidentally" turned on hazard flashers. The first week I had the car I accidentally turned them on 3-4 times a day. Did nobody test this stuff? You almost can't use the touch screen for navigation w/o consciously avoiding this switch.
2) The entire "home screen" on the 2010 cars is significantly better. Fonts you can read, maps you can read. A home screen with a half-screen map. Was about perfect and now this mess on the Edge. I can't read the fonts.
3) Drill down. If you need to drill down many layers of screens to set up your screen or whatever, why does it not remember where you were? You have to drill down again, or just forget about setting things up and learn to live disgusted.
4) Sync. Now it plays CD's recorded onto a USB in alphabetical order, not track, order. What are they thinking?
5) They still have not corrected the metadata tag artist/album artist. Sync uses Album artist as artist, and it is not correct.
6) The touch screen is so SLOW as to be annoying. Why does my phone operate faster?
7) The rear view camera is really bad. It is slow, herky-jerky, it blinks, and barely works in low light. Compare to 2010 models, it is poor. 2010 Flex and Taurus were PERFECT.
What is so annoying is that they had it SO RIGHT on Sync and infotainment on the Flex, the Taurus for 2010. This 2011 is so far down in operational design as to be nearly useless. I stopped using many features I used to use on a Flex because they just don't work well and they are annoying. I cannot believe any real-world testing with human beings was done on this, else it would never have been released. I can't wait for the lease to be up on this thing, I'll get back into a Flex.
The saddest part? The car itself is great. But you interface constantly with the MyTouch and that overshadows everything.
Oh there is so much more to dislike about this MyTouch but I'm tired now.
