Query: Poor Maps for the US

US Maps woefully out of date with no updates forthcoming. They get all the interstates right....Secondary? HaHa....When they have updates, you get to buy them, then you find out what's on them. No way to tell ahead of time....be careful.....be very careful...The routing leaves a lot to be desired as well. Unit tends to favor main roads which are not always the "shortest" or the "fastest" route.
