Nuvi Detour function?
|
|
| Bruce. 2007-06-25, 3:33 pm |
| My Nuvi 650 manual doesn't say much about the Detour function. Does anyone
know how it works?
The manual seems to imply that I select Detour AFTER I've already diverted
from the planned route. How do I use it? Do I select Detour while I'm
still on the route but need an alternative, or after I've already left the
route?
It says it will get me back on the original route "as soon as possible".
Does that mean a block later? 1 mile later? Just how much original road
does the Detour function attempt to avoid?
Thanks!
Bruce.

I would suggest to give it a try whenever you have the chance to see how
it works. Of course if I am driving right now I would give it a try =
myself,
and probably just report whatever I may see.

I tried it and I wasn't able to discover the rules it uses for rerouting.
Sometimes pressing it would immediately do a u-turn (around a block) and
send me back the way I came on to an entirely new route.
Sometimes the new route would just a few blocks different. Sometimes miles.
At other times, it would avoid the upcoming turn. For example, if it said
to turn right in 0.2 miles, pressing Detour changed it to right in 0.8
miles, a later turn. So instead of avoiding the road I was on, it avoided
the next turn road.

I haven't had the chance to try it myself, but just look at thing going =
on
at contruction area that they have the road CLOSED then I figure that the
DETOUR is nothing more than finding another route to go parallel with the
main route (without leading to the DEAD END), and help to get back to the
main route.

It's very possible, because I guess it depends on the route and if it =
can
find another route that about same with the original route then it may =
just
use a newer route rather than trying to get back to the original route to
find the road still CLOSE.

It sounds like you misunderstand the meaning of DETOUR which I think it
means to help dealing with CLOSED ROAD instead of finding a shorter =
route.
Or may be traffic problem like accident.
Also, I haven't had the chance to experience with the MSD Direct yet to
know how well it works with the traffic issue.

In my examples, I expected it to do exactly that, get me off the current
road because it was "closed". Instead of doing that, it actually changed to
keeping me on the current road another half mile before the next turn. What
it detoured around was not the road I was on, but the NEXT road in my route.
Had my current road actually been closed, the new route would have been
impossible to follow.

Bruce-
I assume my Nuvi 350 detour works the same as the 650.
I recently encountered a traffic jam on the Interstate. I took an
upcoming exit and pressed the detour button. No matter what I tried, it
kept telling me to get back on the Interstate, which I eventually did.
It turned out the backup was caused by rubberneckers at a minor accident
scene ahead.
As far as I can tell, that particular exit only goes to a local
residential housing development. In fact there doesn't seem to be any
other way out than the Interstate highway.
Sometimes you have to help the Nuvi. If I had gotten back on the
Interstate going the reverse direction, I think it would have eventually
found an alternate route.

This is what I am guessing the difference between "detour", "off-road" =
and
"recalculating" etc.. and of course with and without Traffic Service.
- DETOUR, we are telling the GPS that the road is CLOSED so it won't try =
to
go back to the original route. But
- Because without the Traffic Service it can't tell exactly how far the
road is close so it may create a newer route for around 1/2 - 1 miles =
or
so, then return to the original route.
- If it find a better route then it may continue the newer route for
miles. IOW, the log/short DETOUR may depend on different situation.
- DETOUR, of course it won't be the best road *but* should be better than
the CLOSED road. Or the option to go around the closed road, strange and
difficult place that it's almost impossible without GPS.
And I guess with the Traffic Service and the problem is reported to the
service then it should have more detail information, and should be able =
to
get a better route. I am guessing the difference that with the Traffic
Service the GPS knows how far or bad the traffic is so it can come up =
with a
better route.

That was my experience. While sometimes it seemed unpredictable and
surprising, like when it kept my on the road I declared closed, it does seem
to work well in most case. I had fun trouring neighborhoods pressing detour
every couple of blocks. I was afraid it was going to curse me for making it
work so hard. :-)

Interesting. It was trying to tell you in its own way the exit was the only
way out.
That's been my experience too. I love the way the Nuvi instantly
recalculates based on whatever I'm doing. If I miss a turn, intentionally
or not, it just issues a "recalulating" and starts over.
But is it just me, or does the Jill voice start to sound irritated about the
4th or 5th time it says "recalculating"? :-)

That's one of the reasons why I miss the COMPASS feature of the old
StreetPilot which always have the compass on screen pointing to the
destination so we have the idea if we drive parallel or further away from
the destination.
See, I started with the older model didn't have auto-routing feature, =
and
it worked similar to Off-Road option.

Yes, my first GPS was an eMap and that one wouldn't do autorouting at all.
All routes had to be pre done on a PC and downloaed to the eMap.
