[CA] [CA11] Problems with Fishfinder

[Chuck - Raymarine - Moderator]

MojMoj,

As improved sense resistor detection is part of the latest software update and the symptom reported is that the type of transducer is changing, updating the DSMs software may indeed address the reported issue. The most common causes for the reported issue is an incompatibility of the CF memory card with the MFD's boot loader or intermittent communications with the DSM. As you had indicated that you had successfully updated the MFD's software, should the same CF memory card have been used to update the DSM, then I would have expected the software update to be successful unless the aforementioned intermittent communications issue was being experienced. Should another CF memory card(s) be available, then it would be recommended that it be used for the software update. Should the failure persist, then the DSM may be sent to Raymarine’s Product Repair Center to receive the software update.
