Just did a major upgrade. Bought both scanners. I have the software installed and did the updates. My question is programing. I have my fav lists ready to go. Before I upload them it wants me to clear all user data. Wont this erase all the stuff on the SD card. My real question is, Will the database still be on the scanner so I can do the zip code thing if I need to. can I do a factory reset on the scanner. What if the SD card needs to be replaced someday. What if I have a disc failure, can I reinstall the software to the PC from the scanner again. Should I buy a new SD card and put the factory one away for safe keeping. Just how fragile is this thing.
