this be a great product . we buy it right before a vacation , and it come in mighty handy . it tell you the name of the street to turn on , rather than just `` turn right in 500 foot '' . occasionally on a busy expressway it may seem that you do not get enough warn where to turn , but , you just have to make sure you obey the 350 when it say `` stay leave '' or `` stay right '' , so you 'll be at the exit and be able to make the turn when it tell you to . we love it .
