SUZ1

SUZ2

From 3490's TEXT file en_GB.glx it seems that the string is the this one
SUZ3
US English is in the firmware and if I select an other country's Text, change these values from "true" to "false" and restart 3490, it automatically changes the TEXT back to US (default text).

I do not know if it's worth the trouble to eliminate this screen, you have to consider the danger of crashing or damaging your device and is not a ordinary Garmin device to bring back to life...
