Check this link to know the detailed upgrade steps.
Make sure your radio is DFU mode before upgrading.I'm encountering a big problem. I have an HD1 GPS, suddenly there is no way I can have the connection with the software or the firmware update working. It always give connection error and I don;t know what to do. The serial port is visible in windows. Any chance to have a support? Could be possible that the cable is suddenly not working? How to test it? What is the procedure to reset the radio from the keyboard? Maybe it could help? Thanks Paolo
