deleting poi from device

You cannot delete the built in POI's in your unit. You can delete any POI's that you load.
1. Using POI loader, load a new set of POI's and that will eliminate the old set. You can group many POI's on your PC (see FAQ's and other postings) and load that set whenever you wish.
2. Using POI loader (beta version) you can erase all of the custom POI's you loaded.
3. If you meant to eliminate a single location, you can edit a POI file (.csv) in excel or wordpad and just eliminate the line and resave as a .csv file.
