We received our 2022 R27 in June of 2022 with the Garmin MFD screens pre-configured (love that! Didn't intend to change anything)

Our latest tank top off July 18th, setting tanks to full and heading back to Elliot Bay, from Des Moines (after having some touch ups done by talented RT staff) we noticed that the "economy" was now reading 0.00? It had been working fine up until "this" tank top off, no issues on the prior 2 top offs?

We powered down both engine and chartplotter twice and the Garmin MFD still shows 0.00 while the Yamaha engine display shows updating mpg. We have "not yet" tried the "hard reset" talked about here on the forum, but some have said the issue persists?

Any updates to this issue? I assume we have "latest" software as of June 2022?

If unable to get "econ" display working, our plan-B would involve substituting GPH fuel flow display rather than Econ on all the affected Garmin display tabs.

We would need to have this done or someone walk us through it.

On each display where you see the economy as 0.00, press the econ on the screen and hold it. It'll pop up "replace data", go to Fuel, and select fuel flow rate.

You must do this on every screen that you want changed.
 
Once again, Thank you Martin & Lazina for your feedback and group support!
