Some functions of LE that I just don't see what's the point

[ted_salad]

OK, I have spent about 15 hours playing with an LE and drive around with it. The device is not that complicated so I have become reasonable familiar with it. But there are things about the device where I don't get what's the point of it being able to do that.

Navigate to, versus prepare route. Let's say you are in a location and you want to go to another location. So "navigate to" lets you start where you are and routes you to where you want to go, you start driving and you end up there. But I don't understand the point of "prepare route". Using "prepare route" I can be sitting at my home in Bedrock, and use it to prepare a route, from 1st Ave and 25st Springfield to 3rd Ave and 18th street in Springfield. But as far as I can figure, I can't save this route as a favorite, nor Save it as an itinerary. Other than the informative value what does it do? It would make sense that you should be able to save it as a route and/or load it into an itinerary. And certainly, "prepare route" lets you start be designating "leave from" and your present location just as the "navigate to" starts you from your present location.

Here's another function I don't get. I'm at my desk in Bedrock. And I prepare a route from Homer's house to the nuclear plant, and I click "show route demo" and I see the route run from Homer's house to the plant. But if I let the TT sit on my desk a while I see it recalculate the route and the navigation now starts from my house in Bedrock to the Nuclear plant as a final destination, not going to Homer's house first.

Itinerary planning; I've read as many threads as I could find about this function. And it's fairly straight forth to use. I read one posting that said that if you mark any waypoint as already visited the TT will not route you there. I can see the possible use of this feature as; I want to visit Comic Book man, Homer and Mr Burns next month, I know how to get to Comic Book Man's place. So I would plan the itinerary as Comic Book Man, to Homer's place to Mr. Burn's mansion. With Homer's place as a waypoint and Mr. Burns as destination. So if I designate Comic Book Man's place as "visited" the TT should make a route starting from Comic Book Man, to Homer's to Mr. Burns.
But what happens is that I get a route that starts me from my house in Bedrock to Comic Book Man's place first, and then the rest of the itinerary.

Comments? Explanations? Anything?

Navigate to..: routing to a destination from your current position.

Prepare route...: I know what you mean, it sounds a bit redundant but I use this often when I fly to a certain location then rent a car to go to my clients. I input the point-of-origin (airport) and client address as destination, let the device already calculate the route and then I switch off the device. When I land and received my rental car, all I have to do is attach my device, switch on, and go.

But if I let the TT sit on my desk a while I see it recalculate the route and the navigation now starts from my house in Bedrock to the Nuclear plant as a final destination, not going to Homer's house first.

Yes, because at this point the device assumes that you already want to go to the defined destination and Homer's house might be out of the way.

Iteneray planning...: always uses your current position as the departure point.

Ahh yes, setting the configuration of the device to start up where you left off when you turn it back on will do this! This seem like the equivalent of saving a pre-planned route to execute later. Which seems to me what making an itinerary should be able do. Turning it off to make it save it seems to me to be an illogical way to have to do this. It renders the device useless until you travel that leg.

Seem to me this is an illogical assumption for the TT to make, for the programmers to make?

Now as you noted up top, using prepare route makes it possible to create a route from anywhere you want to any other place.
It seems tho me that this should be a function of the prepare itinerary since it has a "save" function and you don't have to turn it off.

Yes it seem to always use you current position as a departure point, but that seems to be to also not a necessarily logical assumption for the TT to make.
