Oh I agree...but....
Neither Whistler's newest manuals or Uniden's manuals cover their software (EZ-Scan or Sentinel) - so its a learn on your own. Wish they just posted a few good YouTube videos on the software - there are some good ones for Sentinel but not so much on EZ-Scan.
Sorry but these days and age I refuse to type in a whole trunk system manually. Did that enough during the 80/90's - I do everything via Software. And these companys include the software on the SD cards so they should ad a bit of support. My two cents
