I have a 2005 vintage 1824C / GD-1920C, updated to Program # 195002304.01.06. I have recently purchased a new Navionics+ SD chart card (MSD/NAV+NI US117U1DXW1GZS) to replace the old chart in the system. When I attempt to start the system with the new chart, nothing happens ... the unit starts to hum, but there is no beep, and the system doesn't boot up. When I replace the new chart card with the old one, it boots up normally. Any thoughts about why the new card is not working? Thanks.
