Bad Elf 1000 30-Pin iPod/iPhone/iPad GPS Receiver

I purchased this unit to add GPS to my iPad, and also to be able to use GPS when my iPhone 4 is in airplane mode.
This product works great, exactly as described. You simply plug the unit into the iPad/iPhone/iTouch and it adds native GPS support to every app. I can’t emphasize that enough, the apps you already own work great with it, they don’t need to be updated at all to work.
