When it worked properly, it was great! I got this because my phone's navigation is not reliable-too old. I've been pretty disappointed because it keeps loosing the GPS signal. I was in a different state and got this purposely so I wouldn't have to worry about getting lost, well, I got lost plenty! It not only would lose the GPS signal, it was not able to find major points of interest, like the Mall of America!! I will be returning it. I don't know if its this particular unit so I will be exchanging it hopefully, with better luck.
