I purchased from a dealer the update card to convert my Navionics RDP-149 (ver 4,01) to C-Map. I followed the included instructions to the letter, the unit changes splash screens twice during the update and then beeps repeatedly after a few minutes. When I remove the card it turns off. When I reboot it, the Navionics software is still on the machine. I have tried it 5 times and even completely reset the unit before trying again. Is there something I am missing? Can I download or have an email sent of the software so I can try a different card?
