iPhone Copilot GPS navigator

this excellent app is a turn by turn talking navigator that works like a dedicated Garmin or Tomtom unit but it cost $35, with no additional subscription charges, and is amazing value. It's fast, has a very clear display and easy user interface. To mount and power it in the car I got a Belkin TuneBase FM ($89 at Frys) that plugs very firmly into the lighter socket and has a gooseneck that lets you adjust the position. The iPhone clamp works with a case fitted, and I was able to tune the car FM to hear the turn by turn directions along with the music playing. There is an output jack if you have an aux input socket on your car stereo, and a USB to charge a second iPhone on long trips or whatever else you have.
