Dealer tries so hard to rip me off

You pay $120 and that gets you free updates for the life of the unit! They upgrade the maps 4 times a year, so if you pay $120 and own it for 3 years that's 12 updates!
Yes you download the maps, but if the maps ever get too big (a couple of years later) for the internal memory then you have to put the maps on a SD card. But those are cheap enough now.
This is true with all GPS units.
I think to upgrade once when you buy the unit it's free for 2 months. Then 1 upgrade is like $69, so worth it to buy the lifetime upgrades.
Just a thought.

As far as paper maps go. I use them but my wife isn't as good with paper maps. Hard to read a map and drive in unfamiliar areas for her. So a GPS makes sense eespecially a hands free.
The Garmin 885T is on sale at Amazon.com for under $500!
