If you are using Street Atlas Handheld you can do this
1) Decide which waypoints you want, and use user flags on GSAK to make them a group.
2) Go to file, export, Street Atlas TXT. Be sure the begin note check box is checked. Also note where the file is being sent. ( Prefered location is to My Documents)
3) Click on the button to generate a file.
4) Open My Documents (or which ever location you’d sent it to)
5) It should be labeled sa map txt document
6) Open this file and you should see a list of all the waypoints between the words BEGIN NOTE and END
7) Highlight all the waypoints between BEGIN NOTE and END
8) Cut all the highlighted waypoints, and close this window as well as My Documents if it is still open.
9) Open My Computer on your start menu and find your C drive, then look for the DeLorme Docs folder.
10) Open the DeLorme Docs folder and find the folder named Mobile Maps.
11) Open Mobile Maps and look for the folder named Wpts Transfer
12) Open the file named XMapHHWptsSend
13) Where you see the words BEGIN SYMBOL place the cursor after the word symbol, and hit enter.
14) This will give you a new line so the cursor is between the BEGIN SYMBOL and END
15) Paste the previously cut wapoints into the documents at this time.
16) Go to file at the top of the page and click on save.
17) Now hot sync your PDA as you normally would and the waypoints SHOULD be there. If they are not then throw your PDA in the toilet and go back to paper. TY
Hope this does what you want.
