Looking for MHI2_US_AU57x_K3633 AIO File

[OSHKOSHKING]

Howdy folks,

Trying to update the firmware for my dad so he can use carplay without looking at his phone while navigating. The firmware of the car is currently MHI2_US_AU57X_S0536. (I'm not 100% I even have the firmware I need right). I downloaded MHI2_US_AU57X_K3341 but got a train block error. I'm thinking the K3633 will help me.

Looks like MIB Solution is down (has been for a while for me) and i'm wondering whether anyone would be kind enough to link me to a file they may have stored in a digital archive. Thank you so much in advance!
