Hi,

I was trying to change the language on my A11 radio module.
So I grab calibrations from my vehicle and EU model and replace only the language cal file, the other files remains unchanged.
Programming succeeded, I can see Russian language on IPC but radio, navi and whole CUE does not work.
CUE says this: "Perform calibrations. You must calibrate one or more devices before using the system.
Could you advise what other devices I must re-calibrate to get this working?
Many thanks!

firmware update from usb file transfer

Thank you. I will try and let you know.
When I do SPS2 reprogram it fixes the issue but I would rather avoid purchasing SPS every time I do radio reprogramming :)

I did try USB but it is not working.
The USB have correct installation as it works on other vehicle.

You can collect the calibration files from the GM SPS service, create the DPS archive file, and then use DPS to program the module without needing to use the GM SPS service in the future for that particular vehicle module.

This is exactly what I've done.
I've created two archives. One for my VIN as a backup and the second one has only replaced language calibration file.
Every time after successful programming I got that message. I was trying few archives, always getting same message.
