I didn't want to spend a ton of money on a navigation app without being able to try them out. So right now I have MotionX (.99) and CoPilot (4.99). I really like the aesthetic of CoPilot, especially more than MotionX. However, I have been extremely disappointed in CoPilot when it comes to Point of Interest searches. I have wanted to just try out the apps so as I drove around town I plugged in different stores to use on apps.
Best Buy, Staples, AT&T Store, Apple Store, and a car dealership were my destinations. CoPilot had none of these locations in my searches. All of these places have been located in the same buildings for years. While CoPilot couldn't find a single one of them, MotionX accurately and quickly found every single one.
If the GPS app I'm using cant find major retail chains like this, then I really can't see myself using it. From reading reviews I think TomTom sounds like its pretty good, but I can't see it being worth $50 when MotionX does pretty well for $1. Navigon sounds pretty good too, but $30 for just 1/3 of the US or $80 for the full US is way to much for me.
