Will evaluating a couple of Trucking GPS units they all did the same annoying thing
[rant]
Announcing turns when you dont turn
If i am traveling on lets say I-90 for example, going thru multiple states why do I get informed of turns when I actually stay on the interstate and go forward.
From Omaha to Oakland is a straight shot why do I need to be warned about turning when i don have to?

If the latter... the GPS does not have a camera to see what you see. It knows the Freeway is going to split and is informing you of this.
I see this a lot when you have a "Y" ahead of you.

For the same reason my routes me down a ramp, then back up the other side...when I set to shortest route LOL -
i love my gps--but if i followed its every direction i would
a---be very lost
b---be driving a convertable truck and trailer -
I think most of the issues is where you are on the interstate (I-80) and a highway (30) merges and you it announces to get on highway (30) then when the highway splits it tells you to turn on the Interstate (I-80) when you have not actually made any turns at all...
this scenario is just from memory but on my next trip i will right down specifics if you prefer -
But, yes a "Y" exit will tigger an annoucement.
But, again, in the map database how do they have that road tagged? that would take some details and then we can see how it is entered into the mapping database.
As for exits, all roads are build as segments into the mapping database and based upon that are given a "cost Factor" so to speak. The ramp may have a lower cost factor in the mapping database, so being a computer and following the program it routes that way.
If you are going around a curve it may have you get off a ramp and then back on. That is shortest and fastest to a computer, but the code is written to work around that. If you find the TND doing that, then let me know the information and we can verify the mapping database and how it is set up.
