we Gamin Nuvi GPS seem like a slightly imperfect but quite wonderful personal angel up in the satelite look out for we . the instruction for set up be easy to understand and follow , e , g , change mile to kilometer , change time from CST to EST. . the actual plot of a route be amazing and probably accurate . because of ` local ' knowledge , we ` disobey ' twice to take a short cut , and the instrument very patiently recalibrate its direction . so far its be just fun .
