No U Turn Instruction

 

I was on a road yesterday and punched in an address that was surprisingly off the same road I was on but in the opposite direction. Rather than instructing me to turn around or make a U turn my Nuvi navigated me in the direction I was originally in on to a high way then exit taking me back on the same road. I immediatemy checked if I had U Turns checked in the avoidance menu but it wasn't. In the older map I usually get the U Turn command in this situation. I am trying to figure out why it didn't let ne turn around. It was about 2-3 minutes extra driving.

Personally I find the U Turn command dangerous and unnecessary. Go to the next intersection, turn and find a driveway or parking lot where a change in direction can be made safely. I have a hard time with all the U Turns I see in some places like Phoenix. If you knew the address was behind you why not just take that into consideration in your route.

I have seen something similar myself but not particular to the 2010 maps. Sometimes when a problem could easiy be resolved with U turn (like yours) it will do a U turn and other times, for no apparent reason, it will try to take me an alternate roads to reverse my path. I'm guessing, but perhaps it has something to do with individual road properties at a particular location.

I've also noticed that Nuvis, on occasion seem to make route selections that seem to try and minimize left hand turns. I could be totally off base here.

I didnt know the address was behind until it rerouted me to the same road. Thats why I said the address was surprisingly off the same road in the opposite direction.

U turn capability differs.

U turn capability differs. My old in-laptop Garmin with nRoute 2.6.1 (City Maps 8) often recommends U turns.
My new Rightway RW200 never suggests U turns and prefers right turns (at least when I prefer "quickest" routing -- I don't yet know what it does on "shortest" routing).
The GPS software in my Instinct cell phone recommends U turns. However, it irritatingly says, "You are off route" sometimes. I know that already; that's why I have a GPS!

U Turns

I was trying to figure out why the 2010 map I have did not allow the U turn. The older 2009 map I had did it frequently when I encountered similar situation. if I had know the address was behind me I would have turned around at th most convenient point as a poster asked in his reply. Maybe it was removed for safety? I would rather have the option or chose detourfor a new option.

Don't let the GPSr drive

Having the device recommend a U-turn allows the thinking driver to do just that -- find a suitable place to turn around, such as a shopping center parking lot, that may not be explicitly mapped out on the unit. Lacking a suitable place, one could simply continue until the unit finds a new route via regular turns. The driver must ultimately make good decisions based on reality, regardless of what an electronic device says.

The logic for map to make less U-turn as possible since

local ordinance keep changing and if the gps ask driver to make U-turn and it is prohibited in some local places.

Garmin likes "Michigan" U-Turns

AKA "Michigan Left Turn". http://en.wikipedia.org/wiki/Michigan_left_turn

Some highways in Michigan have no left turn lane or left turn allowed. Instead you are directed to turn right and proceed a couple hundred yards to a specially marked U-Turn lane with it's own stop light. Conversely, you are sometimes required to drive past your intended left turn, make a U-Turn and then turn right. Common in Michigan but rarely seen anywhere else in the country.

Apparently Garmin does not see this as a regular U-Turn because during a recent weekend in Holland MI my Nuvi navigated many of these odd left turns without a single hiccup or "recalculating" even though I have U-Turns selected in the Avoidances menu.

In New Jersey they are

In New Jersey they are called Jughandles.

here in FL, u-turns are a way of life and more times than not more annoying than just having a regular turn lane in the middle.

My c330 tends to prefer driving a block or two down, make 3 rights than to allow a u-turn, regardless of whether I have uturns selected in the avoidances.

No U-turns is the default on a new Garmin

I noticed that avoid U-Turns is set by default. I had to check the box to allow U-Turns .... on a new unit.

Maybe it had to do with the road I was on in that rural city-main street. I was in the same area Saturday but in the residential section. Had a similar situation with an address off the same street located in the opposite direction I was travelling. The unit gave the U Turn this time. I smiled because it may be because I was on main street why it didnt give me the U Turn command then-a few days ago.
