Hank Im glad your trip went well
I too found the traffic function to be useless anytime things get busy in my area. Also not sure why or how, but the traffic events on this seem to arrive slower than they do on my Nuvi 680.
If you think the 7100's display is amazing, you need to get your hands on a Nuvi 760 my friend

(or even a 200).
I'm trying to find the love for the 7100...but it's dying.
p.s. I did the upgrade too, and the button presses are MUCH better now, but still lacking a real 'touchscreen' feel. If you want more evidence of this, look no forther than ebay and search 'navigon parts' , there are always about 10 units in there with broken screens - you can clearly see the users pressed hard on them in specific spots
