Glad you're enjoying it.I got my iPhone today and used the Navigon App (bought from a member on this forum - thanks Ntombi!) for a 45 minute trip. It worked perfectly. I was concerned about polish and ease of use, and I can say that this App feels great to use and is a very effective standalone GPS replacement.
I am using this mount, which, for the price, is great. $9 shipped and has a solid hold.
Thanks for the mount recommendation. I'm going to check it out. Did you order it from that site?
