BT DieselWorks AutoSync Installation guide
Firmware v2.20 and up only (Dec. 2019+ and newer AutoSync’s will already have 2.20 or higher from the factory)
Requires ‘IO4’ (4” screen) or ‘IO5/IO6’ (8” screen) radios. Does not work on ‘IO3’
2014-2018 Silverado/Sierra 1500

Thank you for purchasing the BT DieselWorks AutoSync. The AutoSync is a patent-pending revolutionary
new easy-to-install module that adds many enhanced functional and comfort features to your GM K2xx
truck or SUV. Please be sure to also follow the quick-start guide on the ‘AutoSync installation guides’
page on our website. It is important to register your AutoSync and pair it to your WiFi network as soon
as possible to receive the latest firmware updates and new feature additions.
NOTE: These instructions cover AutoSync’s with firmware v2.20 and up only! To check your firmware
version, access the AutoSync menu, go to page-4, and press “AutoSync info”.
I know these instructions are long/boring, but PLEASE try to at least glance over every page first. 95%
of tech support email/questions we get are simply due to misunderstanding/not reading the
instructions.
NOTE: 2017+ vehicles have several feature limitations and also require one additional minor wiring
change under the dash at the Serial Data Gateway module connector. Please see the additional 2017+
supplement document instructions on our website on how to perform this wiring change/pin swap.
NOTE: Some menu items are shown/hidden depending on whether the vehicle is in the “key on
engine off” mode, or “key on engine running”. If a menu button that you are looking for seems
“missing”, confirm that the vehicle is in the proper mode (engine running/not-running) first!
