How can report this bad firmware??? 1.73.3 (6-8GB)
- Wipe my user data
- The sound are good but need put to MAX LEVEL to ear on good volume
- The Subwoofer ignition NOT WORK, Dont send the ignition signal to run the external amplifier (the icon of amplifier are activated)
Haven't found any way to report to xyauto. Sent email and wechat msg and no reply.
Can try seller but probably no benefit either.
