I bought my 2008 Fusion used (just got it Wednesday - 10/21/09), and I was wondering the same thing! I like the functionality of Sync, but it wasn't in the car I bought, but I wanted the low miles and high MPGs, so I couldn't pass it up. Any ideas/suggestions out there? UPDATE: I contacted a larger Ford dealer in my area and the Parts guy thought there was a way to do add Sync on a vehicle not otherwise equipt. He was going to make a phone call and let me know. He did ask what type of radio I had... my radio does have the Phone button and it has an Aux button as well. He thought that if it had those buttons, it was possible. He is supposed to let me know for sure and also regarding cost/installation. I'll keep you updated.
