iliyan78 CANBUS Junction Box Functions, please read carefully!
1: The basic CANBUS information is SWC, Doors, Lights, Reverse. The rest of the information depends on the OEM main unit
2: A few models need to keep the OEM main unit, then the junction box is only used to decode the basic information. The rest of the information will be viewed in the OEM system.
The CANBUS junction box is not foolproof and will not display the information you need.
The purpose of the CANBUS junction box is to allow the Android radio to display as much information from the OEM radio as possible.
When you remove the OEM mainframe and use the Android radio, the CANBUS junction box needs to send (e.g., Vehicle Controls, Door/Vehicle Info, Sensors, Tracks, AMP, SWC, etc.) information to the Android radio in order to avoid losing vehicle information and functionality, but most automotive OEM mainframes are inconsistent with some having a lot of information, and some having a little information.
For example, a Volkswagen can display tons of information while a Hyundai/Nissan displays little or no information at all. This is not a flaw in Android radios, CANBUS boxes or cars.
