https://market.android.com/details?id=com.alk.copilot.namarket.usa&hl=en I bought it for $5 awhile back. While google is my primary nav, I love having a real nav that i can use without a data signal. Last week I took a "back way" route from central Kentucky to Central Ohio and was without data for most of the 5 hour trip. CoPilot never steered me wrong. Didn't freeze, didn't send me a funky way, just got me to my destination through quite a few highway changes, small towns, etc. I believe the sale is through Thanksgiving.
