Navigation

Thank you Joel. I think UPS only did the no Left Turn (Mythbusters tested this) function, I have not seen or heard of it for anything else. I had delivery by freight and tried giving the trucker easier directions for drop off and leaving, but he took a route through the middle of Downtown and I didn't realize I gave him directions with a lower clearance and he must of had navigation to avoid that. 1. I would like a navigation to tell me "avoiding low clearance bridge, adjusting route" Whenever/where ever I drive I try to avoid certain lane changes, merging etc. Even at home I know where to go and merge that has easier site lines and open merge areas. Im trying to find a navigation that allows for that, and having a lot of trouble finding one that does that.

I just use the Google Maps app on my cell phone. I always look at each turn photo to see if there are any impediments. Also, the Park Advisor app shows low bridges so I avoid those routes. I go to great extremes to avoid metro areas for safety and routing issues.

We get around quite well using a fairly basic Garmin Novi 52 GPS that's a few years old. With lifetime updates, it stays pretty current on routing changes, and the POI (Points Of Interest) files I've added from free online sources alert us to low clearances, upcoming rest areas, fuel stops, etc. Off hand, I don't recall seeing any publicly available navigational aids with "avoid left turns" type of features. "Fastest", "Shortest" type routing is pretty standard, and there are apps and GPS's that will take the height and length of your RV/truck into consideration in routing though.

I have an older Garmin RV 660. I know there are some new ones out, but I'd say it is about 95% accurate. I use it in conjunction with the Rand McNally TRUCKERS atlas. I have the laminated edition. It is really helpful. With the laminate you can draw your route on it with a board marker. It gives a wealth of information. As far as the Garmin goes, I know they have new models available.
