The coordinates at line:
Are the starting ones, but only for the first time that Navit is run. Once Navit lock on your GPS position it will save your last position at "center.txt" file, so on the next load it will use this coordinate for the initial guess. But remember that it will only save the coordinates if it get a GPS lock.

About the killing after 4', some people reported that if running it from terminal, Navit won't kill. maybe you should try it.

About the "ok" button, I noticed that if the road that you are looking for is properly routed it will shows in a drop down list way as you type and then you click on it, otherwise don't. I've tested it with Florida maps and worked, but with some others don't.

One last thing. You edited the line:
at navit.xml file, but just to know, there is no need to edit this line as it will have no effect, since it is disable, as we are using the maps.xml file.
