ST4 to ST4.3 Upgrade

Important - This upgrade program is shutting down end of August 31, 2025. If you are interested in upgrading - schedule it now, please. Send us your eMotimo Spectrum ST4 to be upgraded to the ST4.3.  For timing expectations, we will need your unit from 10-15 business days in our San Diego shop. 1) please make sure you have registered your eMotimo ST4. This is required. 2) Purchase the upgrade option - shipping cost is calculated for your return shipping. 3) Wait for instructions from an agent in our help system. We will be reaching out with questions, instructions, and scheduling. We will typically reach out in a business day or less. Why are you shutting down this program?  It's hard to do these and time and labor and parts intensive.  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 so we want to retire the tooling and
