Suzuki 4 inch SMIS with old firmware

[Hawthorne]

Hi,

I have four SMIS components, two 2" and two 4". They have the following software version installed (data from System Info):

2": 2.2.0
4": 2.0.0

Engine is Suzuki DF250AP, 2014.

The boat is new (to me), but from what I can read shouldn't the 4" have a newer firmware loaded?

Regards,
Jorn
