We reviewed this case. Your vehicle is a European-spec 2018 Infiniti QX30, and its CANBUS data has not been fully captured in the current decoder profile. As a result, the Android unit cannot correctly retain the instrument-cluster navigation, audio information and traffic-sign recognition functions.
This is a CANBUS compatibility issue, not simply a missing adapter for the four unused connectors. Please do not connect or modify those plugs by trial.
Because all functions return to normal when the original head unit is reinstalled, the factory modules themselves are working correctly. A proper solution will require the manufacturer to collect the CAN data from this European configuration and develop a compatible decoder profile or firmware update. At present, we do not have a verified plug-and-play solution for this specific version.
Infiniti QX30 2018 – Android head unit installation caused loss of instrument cluster navigation, audio info and traffic sign recognition.
Infiniti QX30 2018.
Installed a Carputech Android 14 head unit with CANBUS decoder DH-8220507.
After installation:
Navigation disappeared from the instrument cluster
Audio information disappeared from the instrument cluster
Speed Limit Sign warning appeared
Reverse camera still works
Android unit itself works
Diagnostic codes:
U0163-87 – Lost Communication With Navigation Module
U0255-87 – Lost Communication With Front Display
U1427-29 – Invalid Data Received By Front Camera Unit
The original factory head unit has four separate colored connectors: white, brown, black and blue.
With the Android kit, there are no matching connections for these four original connectors, so they remain disconnected.
I have noticed that some Q30/QX30 installation guides show vehicles with only two of these connectors, while my car has four. This makes me think that my QX30 may have a different factory configuration, possibly related to the front camera, navigation or other OEM functions.
When I reinstall the original factory head unit, the system works normally again and the communication errors disappear.
Is an additional adapter or special wiring harness required for these four original connectors? Could one of these connectors be responsible for the front camera and the missing communication with the navigation/front display modules?
Or is a different CANBUS configuration required for my specific QX30?
