I see that Navigon has many fans among the forums and I would like to ask a few questions. I'm on a iPhone 4S and using the latest Navigon 2.0. I bought both Navigon and TomTom a couple years ago but never used either and stuck with my GPS though. Don't ask . I'm planning to make my iPhone my GPS now because it gives me one less gadget to carry. 1. Is the traffic add on worth buying? I want to be able to reroute on top of knowing about the traffic jams. I have a garmin gps that supports traffic but it definitely fails to reroute me to roads that are less condensed. It detects the traffic but still sends me to that congested road. 2. What use is the Panorama 3D view? looks fancy, but is it actually useful? 3. What is a good mount that can be used and still works with the phone in cases? Not talking about otter box size but just similar to a bumper size give or take. 4. Is there a solution to connect my phone audio to my car speakers? For example when Navigon speaks it would be coming out from the speakers like SIRI when connected to bluetooth. Sort of like streaming all sound to my car including music, GPS directions, and SIRI. I have a Mercedes-Benz and integrated iPod cable if that helps. However, my iPod cable does not work with cases. Thanks for your time!
