Question About Navigation Options

....Let's say I want to find hotels in Denver. There's a three selection option that will indicate whether Denver is going to be where I am now ("Current Location"), "a new location" or "at a destination" (sorry if I don't have the exact wording right, but those of you who have messed around with the POI/Category option in the nav sustem will doubtless know what I'm talking about).

I don't understand what the difference is between "new location" and "at a destination." Clearly if there is not currently a destination laid in the nav system it seems to me I'd be looking for hotels "at a new location" (in this case Denver). If there's no destination currently inputted to the nav system why isn't the option "at a destination" greyed out?

I hope I'm making myself clear here.

So TIA for any help you guys can provide.

I think the three location choices are: At current location, at destination (i.e the goal/destination input into the sat nav), and along the route. If guidance is currently not on, I think it asks you whether you want to continue your previous guidance/destination.
