Got lost in Boston last Saturday...had a crappy map to get to the convention center...ended up doubling back through China Town, running in circles. I pulled out my hand held GPS and tried to figure out where I was going, what a mess. About two days later, it struck me I should have used the blue button...what a dummy. : Still not used to having it. I used it once the first day to check out the turn by turn via the radio and have not used it since!
