Mfd12 position data missing

[Wahib]

Hello,
I would appreciate any help concerning this issue,inhad after changing my 2 yamaha outboards.
I kept the same command link plus multifunction gauge and everything is working perfectly,except that from time to time i have an alarm on my mfd 12 concerning position data missing and i loose the gps signal,then it’s acquired again.
Thanks for the help.

What is your primary position source setup for in the setup wizard under global data sources?
