I purchased an Android G13 and installed it in my 2018 Tundra, non-JBL truck. It's a definate upgrade as regards capabilities. The sound quality is lacking, however. It seems to rely heavily on the smaller front speakers making the sound 'Tinny.' I have adjusted the Amplifier/Equalizer in numerous configurations. I am able to get a little more volume from the rear speakers, but the sound from them is muffled and 'Muddy.' The sound quality is markedly inferior to that produced by the original Toyota Head-Unit.
I purchased, configured and installed an Amp Bypass Harness with no improvement to sound quality.
I am using the stock Toyota speakers.
I verified the Model number is QCM6125.
Android version is 13. Kernal 4.13.190. Build number: QCM6125 13 S10A_123 eng.hct20241022.090634 NA
MCU version is: MTCHS_HA4Z_V4.15a_1 Nov 14 2024 15:38:58
CANBUS is set to "08 TOYOTA_CAMRY&RAV4(Simple)"

@Support Dasaita Per your instructions, I downloaded and installed the G13 20250212 Firmware Update. I made a difference. The sound quality seems a good bit better. I hesitate to call it excellent, but it is much improved and acceptible. I Hope to be able to tweak the equilizer setting and make it even better. Thank you for your quick attention to this issue.
