Nuvi Routing To/From Servive Road

I have seen this on two different units - first the older 755T which I
gave my daughter and the latest 3790T. I would have thought they
would have fixed this problem on their latest.

Interestingly as I have owned many generations of Garmins over the
last 15 or so years - this only seems to happen on my Nuvis. Don't
see the issue on my older etrex Vista or even the iQue 3600.

When there is no active route, and I go from a large multilane divided
highway to the parallel service road, the Garmin Nuvi works fine and
indicates as such.

But with an active route, if I decide to leave the route and move to
the parallel road, the unit ignores my position and continues to
indicate I am on the road I was on (including leaving the speed limit
signs the same). I would have hoped it would have least it would move
me and then attempt to recalculate to put me back (the way the older
units do).

But the optimal situation would be to understand that sometimes,
because of traffic or other concerns (like getting off an Interstate
to find a store or restaurant on a long trip), it would continue my
route on the parallel road and route me back from a service road to
the Interstate only if the service road ends.

It also does silly things like warn me about upcoming red light
cameras on the service road even when I am on the Interstate. Now why
is that important?

Oh well.

I am also concerned that the call center people supposed to help you
with the 3790t have been trained but don't have a unit. Only one per
supervisor currently. Not smart - you have to trust your employees -
it's hard to support the customers without a unit in front of you.
It's small enough to have with you. We are not talking washing
machines (LOL).

It appears to be a "snap to" feature. Similar to moving a point around
on a vector drawing program with "snap to grip" switched on. I'm
guessing this is because sometime the satnav isn't as accurate as one
would like so it makes an assumption that if you are within, say, 100
meters of your specified route, the software assumes a location accuracy
error and therefore you are actually still on the programmed route.

As a navigational or positional aid, that might be a bad thing. As a
driving aid, it may be a good thing. I guess it depends on your point of
view.
