Love LOVE mine. Our only problem is that my husband only hears "Turn right" and doesn't listen for the rest of it.... in 1/4 mile, in 500 feet, etc. He just turns right as soon as she says to. So we hear "recalculating" quite often.
I used the Garmin Garage and programmed my own voice. I'm still waiting for my husband to say "Why does she sound so familiar?"
On a road trip with my best friend and we were wondering where to go to eat..... ask Garmin - there's a Red Robin right around the corner. This gadget has saved lots of time, wrong turns, miles, etc.
