I have got the same setup - harness with the OD-LM-01 box with DUDU7 9.5 - on Suzuki Swift AZC33S 2024 - Canbus does not work (tried all this settings here), the unit does not even say if getting any data or signal.. I will search further how to check this..
otherwise harness works - speakers, wheel buttons.. just need to sort out reverse camera as there is no factory one
