New GPS Unit for the car

We've had a Garmin Nuvi 650 in our car for about 4-5 years now.  The map is hopelessly outdated.  The GPS doesn't even know how to get across the railroad tracks on our street.  I priced how much to get new maps from Garmin and the price was $79.99

Ouch!!  I couldn't believe that price because you can buy a new GPS unit for that price.  So I did just that.  I stopped by Costco on my lunch break today and I picked up a Magellan RoadMate 2036-MU for $79.99.  Pretty pathetic that it was a better deal to buy an entirely new unit than to upgrade the maps.
