[CA] [CA11] Problems with Fishfinder

[MojMoj]

1. I swapped the transducer with Airmar P66. OEM Part # E66054 that on the Airmar website is compatible with the DSM30.

2. I upgraded the firmware of the C120 classic to the latest as of today.

3. I attempted to do a firmware flash of the DSM 30 and that failed. I put the CF card in. Turned on the MFD. Chose Bootloader firmware. Chose Update a Remote Device. Chose Update via Sonar Port. Powered up the DSM 30. Then I get the below error:

A fatal error has occurred -- Assertion Failed: (false) in
File "..\..\..\..\..\..\Source\Bootcode\Tools\Pandora\Upgrade\RemoteUpgrade.cpp" at line 460

Please contact Raymarine's Product Assurance Department providing details of the events that resulted in this error

Am I doing the update wrong? Do you have any suggestions?
