R8 surf Garmin not accurate

[Strudel]

Got R8 Surf out of winter storage and Garmin gauges are not accurate.
No air temp
Fuel not being consumed - stuck on 55 gallons
Trim gauge not working
Depth not accurate
Volvo engine gauge seems accurate.
Water temp is accurate.
Any ideas?
Thanks

You could go into the settings and do a factory reset on the gamins and see if that help. That's the only thing I would know to do, I'm not at all mechanical. There are some smart people on here that will have better solutions I'm sure. Hope it's something simple.

The reset did not result in any improvements.
I have dual screens. I performed the reset on one of them but looked like it reset both. Today I will try to reset the other screen to see if helps.

Well they are both connected so it should have reset both screens... Sounds like the problem goes deeper than just the Garmin. Beyond my scope of expertise. Next I'd try updating the gamins to the latest software. if that doesn't work you know it's not the Garmin.
