I have my local system loaded into my PRO-106 split up as scan list 1,2,3,and 4. I would like to also have a system in Indiana loaded since I drive through there 4 times a week. I think the way to do this is to load it as scan list #5, but doing that only overwrote my local system. Can someone tell me how to make this happen? I'm very new to this loading with a PC digital scanning.
