I prefer to use my brain and an old-fashioned map for navigation but if I had to choose one of those i'd definately go with Mio. As for which model, I really don't have an answer. It depends on what features are you going to need. I would choose one with pretty basic features. One with bluetooth propably because the features that use your phones internet are pretty useful sometimes. Other features are rather pointless because they are the same that are found on most peoples phones.
