I was wanting to ask if the inbuilt AIM-CUE module on this ISR (1861) on the SRST/F models (non CUE) can be soft upgraded in the field to support CUE with the proper licensing? Ours has the RAM and CF card in the units, just no integrated-service-engine shows on boot or on show diag. We were wanting to know is that a firmware limitation or hardware limitation. Thank You
