My wife's 2014 XTS Onstar module will become obsolete with 2/3G phase out in Dec '22. I find threads detailing upgrades/swaps for same year (2014) CTS upgrades to 4g_LTE modules. Not finding similar onstar module swaps for XTS. I believe 2015+ model year Onstar module has LTE/Wifi. Has anyone successfully upgraded a 2014 XTS with the later module?

Thank you. As far as I can tell that upgrade is not being offered in the USA. Onstar representatives tell me it is physically impossible to do an upgrade, which I know is horses#it - especially since you had it done in CAN. It’s a matter of identifying the correct module and flashing it to my VIN. Possibly (probably) an antenna update also.

Did your RO have any part numbers associated with the repair?

Where are forms located online Thanks.
I am in Canada..mine was 2G, so they told me to go to activate.onstar.ca, once I entered the VIN, it told me that my module had to get upgraded. From there I selected my preferred dealer and submitted it the online form. Took them around 2 weeks to ship the hardware out.
