Yes, eventually when time permits, I plan on finishing the sound play tab of the POI scanner. There one will be able to select which sound file they want to be played for the alert instead of having dings, chimes etc for alerts. The added bonus in preparing these files is that they also benefit users of other brands of GPS devices. Newer devices can play MP3 files. These can used to substitute the standard alert when a POI activates it.
I also intend to add code for the scanner to indicate the range of detection since a user can select different distances for the scanner. I've found I tend to forget which I selected. So the scanner might play a message like "airport ahead" then follow with "distance 500 meters" if this was the distance selected in the distance tab.
