Just a heads up that if you bought your 2016 Chevrolet Spark before May 2017, then the LG BYOM2 infotainment system can be updated by your dealer to the 05.02.2017 build to:

• Fix Android Auto audio and voice (navigation prompt) stream separation, so that you'll be able to set music and navigation volume separately.
• Fix loss of Bluetooth audio at the start of stream (very noticeable in navigation, turning "In 1 mile turn right" into just "e turn right").
• No longer show the second USB input in source list.
• Remove simultaneous CarPlay/Android Auto mode (not sure whether that's an upgrade).
• Possibly other fixes.

BYOM2 - Bring Your Own Media v2 system was running on Sparks from 2016 to 2018, then replaced for model year 2019 by INFO3 system running a version of Android.
