Don't know about the others, but mappoint uses fuzzy logic for the searches, so if you search by place name, it will return all results with the same or similar place name. For example if you enter "Convection center". It will return all results that sound like that and if they are sorted by distance to your current location, the correct one will probably be at the top of the list. This does have some tradeoffs to restricted input systems, but, at least with mappoint, you don't have to enter in a city, state, or zip or even spell it correctly, just a street or place name. Also with mappoint your database is very large, i.e. the whole US and since you don't have to restrict results, it doesn't effect the performance of the input system much.

Now that we have voted, let's go and beg for it lol... think how well navivoice would work for entering new addresses... Woooohooooo

The only thing I can think of is for that feature to be implemented in FD or MM. Can't really do this with iG

Yes but disabling keys that really "cant" be pressed is better solution for the OSKs IMO... like the mercedes has

I can't see how this could be coded, it would be a nightmare and probably very slow if it was implemented, it would be better not to have the key disabled but not to allow the autocomplete update.

If designed properly, it would not function poorly. As a software developer myself, I think this would be a fairly easy thing to do. More than likely, an index generator for your current region would need to be rewritten, to pregenerate easy to use data indexes for prepopulating searches that will run while the user is inputting. It's really quite simple.

Indexes that would have to be created:

1. single digit index containing counts for number of associative matches (i.e. a 869,343)
2. single digit directive to double digit index containing counts for number of associative matches (i.e. a ---> b 10,341 --- meaning there are 10,341 street names that start with "ab")

repeat #2 for every potential column (i.e. the longest word in the database).

The advantage of this method is that it would be very simple to check a small index of these to determine what the next available letters are.

So, let's say the user has already typed C, the index might contain something like:

C 3
CA 1
CO 2
COL 1
CON 1

We would know there was 3 states starting with the letter C, only one starting with CA, and two starting with CO. If the index is stored properly, you'd be able to programmatically determine that the A and O are the ONLY usable keys next. This eliminates spelling, grammatical errors, etc. And it will allow for autocompletion or suggesting the remaining spelling. When the user presses O, then the A and O delight, and L and N light up as available.

It is a feature that wouldn't take too long to develop in my opinion.

Seeing as there is no open source mapping extension (i.e. MapMonkey nor FreeDrive), this can't be added by myself.

But to say is it an unimportant feature, or that it would be too slow, is truely avoiding the idea altogether.

Here is the wheel you're so diligently trying to invent

With suffix trees you also get a very nice autocompletion property. See more on the topic.

Here's an image from the stock Toyota Nav system

Yes this would be nice.
But I think it would be better when you can switch with a knob through the letters.
So you only need small place on display and it is better to control while driving.
Is this possible?
