I've been going between an actual gps unit and an app for the iphone. One thing that looks cool is the tomtom app because you can get a mount for it. The only downside is that it looks like I would have to take off my incase case for that :/ Are there any other car mounts available for the iphone, if so, what are some other great gps apps? Also, would I have to pay separately for updates? I have a charger, so Im fine with that. Any other suggestions? Ive heard of Navigon, but havent seen many opinions/reviews of it mainly because I havent bothered looking. Any suggestions on mounts though? I have a belkin car charger with the cable, so something that goes near the center console would be sweet, maybe something that clips to a vent or can mount on a curved surface. My car's(Buick Rendezvous) dash seems like its all curved and what not.
