Upgrade service to convert your existing 2007-2014 GMT-900 AutoSync unit to a 2015+ K2xx AutoSync unit.
NOTE: YOU MUST PUT YOUR CURRENT AUTOSYNC SERIAL NUMBER INTO THE "ORDER NOTES" AT CHECKOUT!
NOTE: Some first-generation 2007-2014 GMT-900 AutoSyncs cannot be updated/converted unfortunately. If you purchased your AutoSync after (roughly) April 2018, you should be OK.
NOTE: If your new truck is a 2017+, you will also have to do the SDGM bypass wiring modification/pin swap, or purchase our SDGM bypass harness.
