Exactly the VS ultra will NOT scan in white springs unless you enter in the tps manually.You MUST modify the .sat file or enter it in manually to get it. If you load the same info in the 2300 it will scan them in also. When you have to enter in the same info to me the boxes are doing the same thing. To me this means that without that info you have no true blind scan. But if you ask a 2500 to scan it , it will pull it in every time.
