Need Hiworld LS08/LS430 High protocol for Reglink CMZX65-U1 head unit

[Lexus_LS430_2004]

Hello,

I need technical assistance with a Hiworld CANBUS decoder for a 2004 Lexus LS430 with factory navigation, Mark Levinson audio and High Level configuration.

Head unit:

* Model: CMZX65-U1
* CPU/platform: MediaTek MT6765
* Software platform: Reglink
* Configuration: 8 GB RAM / 128 GB storage, N4 camera
* CAN protocol version: 26102101
* Protocol box version: Unknown
* Current CANBOX selection: Hiworld → Toyota
* Seller: RSNAVI Android Store

CANBUS decoder:

* Manufacturer: Hiworld/LHL
* Model: LS08.10
* Full code: H1S3LS0810A 210120
* Additional numbers: 2117370141 / 3110519860
* Manufacturing date shown on label: 25.11.05
* Compatibility shown on label: “Fit for: 04–06 LS430 High Level”

LS08 is the correct Hiworld decoder family for the 2004–2006 Lexus LS430 High Level. However, the CAN protocol database installed on my CMZX65-U1 does not contain a Lexus LS430 or LS08 profile.

The Hiworld → Toyota list contains Lexus NX, GX, LX, CT, IS, ES and other Lexus models, but no LS or LS430. I have already performed both the complete head-unit system update and the separate “Update protocol version.” Nothing changed and the LS430 profile was not added.

Current symptoms:

* HVAC control through the Android screen does not work.
* Steering-wheel multimedia buttons, including track switching, do not work.
* Unrelated Toyota/Crown profiles may display an HVAC interface, but commands are not transmitted to the vehicle.
* Android, CarPlay, music and the rear camera work.
* The required original-radio connector was reconnected, but this did not restore HVAC or steering-wheel controls.

The seller’s installation instructions show a different decoder system and require the following profile:

LZ(HZ) → Toyota → Lexus LS460 → HIGH

My actual decoder is Hiworld LS08.10, not LZ/Luzheng. The CMZX65-U1 menu contains a Lezheng section, but the Hiworld section does not contain LS430.

Please confirm:

1. Does the Reglink/CMZX65-U1 platform support Hiworld LS08.10?
2. Is there a specific Reglink host-side CAN protocol APK, database or model file containing the Hiworld LS08 / Lexus LS430 High profile?
3. If it exists, please provide the exact file and installation procedure.
4. Is an LS08.10-specific .iap firmware required for decoder code H1S3LS0810A?
5. Does “Protocol box version: Unknown” mean that the decoder is not communicating through the UART connection, or does it mean that Reglink does not support this decoder?
6. If Hiworld LS08.10 is not supported by Reglink, is support for it planned?

I am specifically requesting the LS430/LS08 protocol for the CMZX65-U1/Reglink platform. Please do not provide a generic MT6765 system firmware or an IAP file intended for another CANBUS decoder model.

Thank you.
