So I borrowed my neighbors usb cord from his home patrol, figured out how to download Sentinel I believe,to computer but can't get it on the scanner. Tried everything I could think of. New 32 sandisk, followed directions on, on-line owner's manual, went on homepatrol.com, read and followed what it said. Nothing works. Can't operate the unit on just batteries. Still keeps reverting back to the same start-up menu.
I put the original sd card back in, yanked the batteries out and will look for a few more ac adapters.
How frustrating to spend this kind of money on a scanner, to have it fully operational for 7 months and decide it wants to half work. Never again. And then they want you to spend more money for more programming etc. Not me. No more Unidens and maybe no more scanners unless unless it can be had of no more "download this software, firmware, hardware" bs. Why not just sell a new loaded micro sd card for a FAIR price and all you have to do is put it in?
