ALK has updated their CoPilot Live GPS application and is available for download from either their website or your specific application store (App Store/Android Market)
I've been using this for my DroidX since November and it is a nice, offline (no internet connection needed) GPS application that offers some great features for $5 (the Premium version is only $10, but the special pricing expires on July 5th). You can review the features at their website.
It includes true GPS application features that mapping tools like Google Navigation don't provide, such as current speed, speed limit warning, etc.
