ST4 to ST4.3 Upgrade

Important - This upgrade program has been shut down September 30, 2025.

Why are you shutting down this program? 

We offered this program to users initially that just missed out on getting the ST4.3 option when it came out and to support our loyal customs with new functionality.  We have given those users plenty of time upgrade (over 3 years) so we are retiring the tooling and expertise needed for this.  

If you are the original owner of your ST4 and interested in options to get the latest head, send us a email to sales@emotimo.com.
