  I recently installed a Dasaita G13 head unit (Model: HA2272H-G13a-CP-2K-4) into my 2010 Toyota Tundra. Everything works great except for phone calls.

  I plugged in the included external microphone, but whenever I make or receive calls via Bluetooth or Apple CarPlay, callers tell me there is a noticeable 1–3 second delay when I speak.

  System Info:

  • Model: HA2272H-G13a-CP-2K-4 (Qualcomm Snapdragon 665 / Android 13)

  • Build Number: QCM6125 13 S10A_123 eng.hct.20260409.193809 NA-V1

  • MCU Version: MTCHS_HA4Z_V4.17j_1 Jul 3 2026 19:33:22

  Questions:

  1. Is there a known MCU or system firmware update that resolves microphone lag on G13 units?

  2. Does plugging in the external mic cause a dual-mic conflict with the internal mic on these boards?

  3. Are there specific settings I should adjust to fix this?

  Any insight or links to recent G13 firmware would be appreciated!
