To prevent some of the repeat questions which have been answered on the Navigon iphone website:

Looks like Text to speech might not be free, by the way, in the video that shows/says "exit onto I-5 South" IS text to speech, but it is only programmed to say "I", numbers and direction (south, north...etc). This current version does NOT say
street names, but as the above text says, it's coming...but maybe you have to pay.
There is also no data, this app is 1.2 gigs with maps and does not download the maps "while you drive" over the mobile network. So if you are in the middle of nowhere, it will still work!
