To do the download, you will need programming software. For your scanner, you have a choice of ARC500, Win500, and PSREdit500. Some people have been having problems getting keys for Win500 and the site goes down quite often. There is a question if the author of the software is OK. Each has a free trial period. I use Butel ARC500 and am very satisfied with it. What is your city and county and what in particular would you like to monitor?
