Hi 206nolan

The card that you have which is 8gB, is this the chart card? You may find this link that is here usefullif your 8gB card is full with the sonarchart data.

The MFD does not store the 3D Realvision data on the mSD card, but it does store the sonarchart depth information

What cartography are you using? Navionics or CMAP?

We advise do not use the chart card to load software updates as well, there is a possibility the software update could corrupt the chart card, so always use a different micro SD card for the software updates.

What MFD are you using?

Can you check SONAR LOG in DEPTHS and CONTOURS is turned OFF as well?
Are you also recording track points as well,possibly you have exceeded the maximum number of track history points allowed? Try reducing the distance between track points and increasing the time between recording points.
