I searched for a similar thread already and couldn't find one, so I apologize if there is one discussing the successes/failures of this app. 1. It works. I put it to the test by traveling to a couple places that were 30 minutes away that I had never been to before. I got there successfully without much confusion. 2. The GPS signal is very sensitive. Placing the phone in your lap while you are driving causes the app to lose the preciseness of the GPS signal, and you WILL miss directions. It NEEDS exposure to the sky. I put it on my dashboard and the app became flawless. I just bought a windshield mount so that I can see the directions while giving it the proper GPS placement. 3. Some of the directions are whack. Now, I have no experience with dedicated GPS units, so I have no idea if they do this as well. However, it will take you on some really weird routes. Some of them are terrible suggestions; some have been helpful! 4. If you get a phone call, like other apps, you have to re-open the app and then when you get to the View Map button, it will ask you if you want to re-use your previous destination. It will then talk to you at the same time your caller speaks. You have to hope you don't miss any important directions if someone calls you before you can re-open the app. 5. Currently there is no integration with the iPod of your iPhone. When you open the app, the music stops. If you have headphones with the remote controls, you can click the headphones to get the music playing again. This will silence the voice directions. Most likely, you are not wearing the headphones in the car. Therefore, once the app silences the music, there is no way to get the music playing again. Double clicking Home closes the app. It does not bring up the ipod controls. I emailed the developers and they said they are working on fixing iPod integration. How has this app worked for you guys?
