[CA] [CA11] a95 boot and touchscreen issues

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum wingman,

Typically, the symptom reported is resulting from operating the system with older software or a fault within the software. Less frequently, but still possible, the chart card media or the MFD's memory card reader is at fault. Accordingly for those experiencing such symptoms with an a/c/e-Series MFD it is recommended that

- the version of software which is installed within each of the system's devices be inspected (HOME->SET-UP->MAINTENANCE->SELECT DEVICE) and if any are found to not be the latest, that the software within the system's devices be updated with the latest available Raymarine product software updates ... it has been noted that the MFD's software has been updated, but it has not been determined whether the software within the system's other devices have been updated.

- the Chart application's Sonar Logging feature (MENU->PRESENTATION->DEPTHS & CONTOURS->SONAR LOGS) be disabled.

- a System Settings & Data Reset (HOME SET-UP->MAINTENANCE->SYSTEM SETTINGS & DATA RESET) be performed ... it has been noted that you have performed this step. However, should the problem occur afterwards having disabled the Sonar Logging feature, then it would be recommended that the reset be repeated as well as to once again disable Sonar Logging

- Should the problem persist thereafter, then it would be recommended that the MFD be switched OFF, that the Navionics chart card be removed from the MFDs memory card reader, and that the MFD be tested again. Should the problem abate, then it would be recommended that the MFD be tested with another Navionics chart card and if found to abate, then the chart card should be replaced.

- Should the problem persist or no other Navionics chart card be available for testing, then it would be recommended that the MFD and Navionics chart card only be sent to Raymarine’s Product Repair Center to be bench checked / serviced. One symptom of a failing touchscreen is that it will flood the MFD's processor with commands, causing it to be unresponsive to screen touches and button press (ex. a quick press of the MFD's Power button to display the Shortcuts dialog).
