Addition for Nav4All: I found a replacement for the Holux GPS viewer that works better. BAF has come up with a today plug in that toggles the GPS. Here's the link

Also, found that the "exit" option works poorly with N4A (doesn't release all its memory back) and its best to use the OK hard key to exit the app and then kill it with one of the task managers as it clears the memory better.
