Unable to update software in DSM300

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Mike,

Please click here to view a thread in which I had previously addressed this subject. It should be noted that no software update should be performed to a DSM30/300 unless seeking to address a NO DSM or DSM CONNECTION LOST condition ... and in the case of the latter, problems within the DSM may prevent performing the software update. Should the system be suffering from the above listed problem and the procedure attached to my post within the referenced thread not permit a DSM30/300's software to be updated, then it is recommended that the Raymarine’s Product Repair Center to be bench checked / serviced / serviced or that it be replaced with a CP370 Sounder Module.
