Having such a unit with GPS in my Wife's 2010 Ford Taurus Limited I must agree it does seem too complicated, but have never had an issue with it. Some really neat features like "Live" weather radar maps and better traffic conditions reports, but you have to find them to use them. Wife does know how to use voice commands, but I like the 2007 Nitro interface that requires touch screen commands, myself. I understand many have said their units are hard to use, and Ford is on record stating they plan to simplify SYNC in future models. I have downloaded updates to her unit and installed them with a memory stick. Chrysler's 2011's complete new system I'm sure is an improvement over what I have.
