The new-fangled GPS technology is designed to make sure you won’t get lost on the way to grandma’s house. But Nudar turns your standard GPS system into a granny-hating “nude radar” that leads you to strip clubs, nudist beaches and anywhere there’s no underwear. In addition, it will let you know if the nearby strip club is all nude, bikini, pastie or topless (granny’s favorite); if it offers a full bar or is BYOB. It supports Tom Tom, Garmin, Magellan and a few others. Sign up now for a 30-day free trial at Nudar.com.
