Since I haven't owned either unit, I thought the MFT was pretty cool. Nothing to compare it to but the Nav unit in a GM car I own. Man, that one is crap.
Also, here's a good one. I have no idea if this is true. I was told by the salesman that the MFT Nav. unit in the new F-150 will automatically update through google maps with no charge to the customer. Duh, I don't know...do any of you?
