2018 Sierra WT io4, io5???

[Knowles101]

So I have a 2018 Sierra WT and I'm trying to figure out if my HMI is io4 or io5? Any way to do this without taking out the unit?

The last email we have from anyone named Eduardo was in March and has several replies on both sides.  If you contacted us and asked a question outside of what’s covered on the website (which has all of the Denali cluster info) you’ll want to check your spam folder.
