RayMarine c80 MFD replacement options

Card reader on c80 MFD went out on me. Any ideas?

My MFD recently died and I have been using my nexus 10 with the navionics app

Seems to work well locally. No idea how it wouldn’t work out at sea. I mount it with this

Only complaint is battery life. Planning to run a USB power wire in the near future

Hope this helps
