Garmin NUVI, 200W NAVI unit. Saw it for a decent price by me $189. I was ready to throw my 4 year old Magellan out the window on my last trip, because it is a real PITA to enter addresses and does some really goofy routing. Plus the cost of the database update was not worth it.
This NUVI is slick. Large screen and about as easy to use as you could get. One drawback is the short window mount. Makes it tough to reach when on the glass.
Haven't done it yet, but some guys at work have loaded the custom POI lists off the net. I would think someone has a CG list around.
