Nav System

I am traveling in New England this week on vacation and making good use of my $120 super cheap Chinese made navigation unit. It has been pretty good so far except for the couple of times it froze up completely and a few times it completely got confused. I keep seeing ads for expensive models that have the ability to reroute you around backups which at first seems like a great feature. But the reality is as more and more of these devices get onto the road and become affordable for everyone, the route around backups will become the new route because everyone will be taking the side road. So I guess its a matter of enjoy it while you can, since there are a limited amount of optional routes that can be used by an ever increasing amount of vehicles.
