If you are in the XChange2 app and using the GoogleMap there, it is very simple to do. You have to be logged in, so that you have access to GoogleMap. Then zoom in on the area where you have found a location that you want to detect. Once zoomed in, just "grab" the CREATE WP icon and drag and place it on the location where you want to detect. If you have only zoomed into the map and not opened a COLLECTION, you will be asked to select a COLLECTION. (So if this isn't to be included in an existing COLLECTION, you should create one before creating the WP). Once you have either selected a COLLECTION or created one, the EDIT WAYPOINT box will pop up. This will have the Lat/Long coords in it, but you will need to name the WP and add any notes you want. The name is restricted to 20 characters. The time/date can be edited as well. You can use Lat/Long coords that you already have from some other source, for the creation WP locations also. To "dummy" WPs with known coords, just zoom in anywhere in GoogleMap and create a WP. When the EDIT WP box comes up just edit in the correct Lat/Long coords and finish off like mentioned above.
If you happen to have a find that you, for any reason, don't have a FP for but would like it added to you records, it's simple to create one. Of course, you either have to be able to go select the find location from a source such as GoogleEarth or GoogleMap (something that gives coords) or have the correct Lat/Long coords from a handheld GPS.device. Then scan your find, in your yard or wherever the GPS will function. Once that is done, send that FP from the CTX to XChange2 and open it (obviously it will appear on GoogleMap in the location that you just scanned it). Once the EDIT FINDPOINT window is up put in the correct Lat/Long coords and any other info. You will not be able to edit the Target or Mode information, but name, time/date, notes, pictures can all be edited. There is a quick way to get the Lat/Long coords, for an item that you can go to on GoogleMap. Just drag the CREATE WP icon to the location of the find, copy the coords and use them to edit FP.
That may have made that sound complicated, but it is very simple to do.......HH
