1. Added Equalizer function;
2. Added In-Vehicle mode (connected with car via USB cable and powers on/off automatically when car engine starts/stops);

5. Improved the low-power notification, preventing redundant alerts;

Notes (please read this carefully before upgrading)
a. After the firmware is upgraded, it cannot be downgraded. Trying to downgrade may cause the unit to malfunction;
b. How to check the current firmware version: open FiiO Music app and enter Settings->BTR3. If the current version is below 1.2，you should upgrade the firmware;
c. The Equalizer only works when streaming in the SBC, AAC, aptX, aptX-HD and HWA(48kHz or lower) codec. It does not work for the LDAC codec. And for HWA 96kHz, it's suggested to turn off EQ, otherwise there might be noise.
d. Please update FiiO Music app to the latest version(Android version 1.1.2; iOS version 1.3.9) if you want to use the new feature EQ from "FiiO BTR3"/"FiiO BT Control".
