I have a new 595LM. it's guidance doesn't make sense. For instance, i'll tell to navigate home: *it's always trying to send me down side roads, private driveways, telling me to uturn, all kinds of chaos like that... I'm like: good thing i use it more for correct speed, and to see corners ahead, b/c if I truly didn't know where i was and where i was going, I'd get so turned around i'd never get home. /// But that begs the question, which of course is: WTF!!!!! Now before you get all rowdy and say i simply need to update maps - this is basic arkansas here, every damn road i'm going on and through has been there and un-changed since before Garmin existed as a company.......so I don't buy that a simple map update is the root cause. No no no, i'm not on Garmin ADV routing, i'm on shortest time routing in options/settings. // Another example: i'm 1 mile from home, it's a straight shot down a 30yr old street. GPS tells me to turn, go over a block, turn again, come back to same street, and make a that mile twice the distance.
