Well, I figured out where the select button was to calculate the roots in this application. There are actually a few things about the TomTom app I like better than avigon. For one thing, you can go back to the main menu during a root and select the "help me" option which will tell you where you are while the app continues to provide guided instructions. Also, I have not found a way in navigon to get a list of instructions for the entire root, but the TomTom app will do this. And, if you have TomTom and navigon, you have an app that uses both of the major map providers, since TomTom uses teleatlas and navigon uses navteq. These 2 apps are my favorite ones for navigation on the iphone, I also have one called kapten GPS, but I don't use it as much, it's a bit more difficult to find things I think. Has anyone tried the magellan GPS app? I heard at one time that it wasn't accessible, but I heard the same thing about the TomTom app, and that app works quite well now.To change your email settings (unsubscribe, digest only, or vacation mode): http://senderogroup.com/social_media/email.htm Additionally, to unsubscribe send an email to gps-talkusers-request@xxxxxxxxxxxxx with "unsubscribe" in the Subject.
