Want something better than that droid-ish voice that sometimes tells you to turn left into a park bench in Google Maps? Think TeleNav or VZ Navigator are too expensive at 9.99 per month? CoPilot, a company that's been making mobile navigation software since the days of the old Palm Pilot and Pocket PC has an offer you might not be able to resist.
They're selling CoPilot Live USA for $4.99 lifetime, with no monthly fees unless you want the traffic reporting add-on which costs $9.99/year. CoPilot works well and it has voice guidance, turn-by-turn navigation and 3D maps. Map data is stored on your Android phone, so you don't need an active data connection while navigating.
