650xi & 430w voltage requirements

[Jdm]

We’re considering having a 430w swapped with a 650xi but not sure about system requirements, or compatibility.
Both units are already installed in different airplanes.
The 430w is in a 28v aircraft.
The 650xi is in a 14v aircraft.
It appears that they made versions for 14v, 28v, and a version that possibly works with either?

Does anyone know the deal on this and if it’s even possible?

Thanks,

For the 650xi, from the Garmin website:

• Input voltage range: 11 VDC - 33 VDC

So you shouldn't have any problem putting the 650xi into your 28v airplane. But you better check with the instrumentation experts here about what you might need from Garmin to make the change.

Whew, that’s good news! Thanks for the reference.
