  Hello,

  I've got a 2011 Toyota Venza (with screen, nav, JBL). I'm not getting any sound out of my rear speakers, only the fronts.

  I've tried with and without the RCA harness accessory.

  I've checked the Amplifier settings and ensured everything is unmuted, and moved the positioning to the center.

  Order # SP-DA9750
  Build # QCM6125 113 S10A_123 eng.hct.20250903.190343 NA-V2.1
  MCU Version # MTCHS_HA4Z_V4.16f_1 (Jul 30 2025 16:20:57)

  Additionally -- what's the correct CANBUS setting in factory settings? I noticed currently it's set to none. My order came with Simple soft RP5-TY-102.

  These are the compatible toyotas for this canbus kit. Try any of these models under "simple" manufacturer and check which of them works better with the most features.

  I'll give it a shot. Any ideas about the rear speakers, though? That's my primary issue I'm trying to solve.
