How much is the unlock for wayfinder? It may not be worth the money. I recently bought a Magellan Maestro on sale, with very new maps of the US and Canada, for $170. It's a very nice unit, and has a good UI. It's far better than what you'll get with Wayfinder, I think, and most lower-end GPS units would be a better value unless the price of the Wayfinder unlock is <$50.
