[aprssig] APRS in Garmin

I sent an email to Garmin about the APRS integration issue some months 
ago, I have a GPSMAP60CS which has the duplicate/multiple waypoint issue.

The $GPRMW is a waypoint update sentence, you still need to create the 
waypoint first.
This can be done when the APRS receiving system you are using first 
powers up and receives an APRS station frame (my HamHUD does this very 
well), but what happens when that "new" waypoint still exists in the GPS 
from a previous session? Will there be a duplicate waypoint created 
which will then be updated with the $GPRMW message?
And then you will still need to delete old information somehow, is there 
a delete waypoint message? Can a waypoint be created with a time limit? 
This would be ideal as your GPS display would then only keep relevant 
and recent received APRS info in it's memory.
