Query: good GPS

So far it fits the requirments I needed. The best thing is it has shopping menu which contains all kinds of stores address. Basically as long as you know the name of the store, you can go there. Also it is the same for gas station. But I have to say it's not updated so well. Once I want to find the nearest shell station because I'm almost ran out of oil. But the addresses is wrong, TWICE. I'm very close to call someone towing my car that day. So if you want to go to some gas station, go online to confirm first.Other things are really good. Especially when you know the accurate address of the position you want to go. There are so many similar addresses with slight differences aroung. Like south, north, Dr, Blvd, or just different city. It's very confusing when you just look though the paper map. The only thing you need to be careful is that don't enter the wrong name.You definitely need one.
