I have used both Garmin and TeleNav and I must say that they both work extrememly. I was actually quite surprised. They are both a little bit different. Garmin displays a map with a triangle on the screen (representing your location) while TeleNav gives you turn-by-turn. Although I like seein a map I actually preffered TeleNav because the maps are loaded via Vision so sometimes it may take a while to load a map and vision is constantly being used while TeleNav uses vision periodically. TeleNav has a better UI in my opinion and has more options plus the directions are better and it gives you route types while Garmin doesn't. TeleNav also re-routes much faster than Garmin and the voice directions are louder and clearer. I would recommend TeleN... (continues)
Your welcome. It becomes a little confusing when there are two apps that do the same thing and the same price ($10 which is a little steep) and you don't really know which to get. I downloaded Garmin first becasue I was told by a rep that TeleNav was only a business finder with no directions then I heard that that was not true so after trying Garmin I went for TeleNav. Garmin makes professional GPS systems but TeleNav has been providing GPS Turn-by-Turn services for a while for Nextel so I figured they would probably be better and IMO they are.
