Sorry, but what do you expect?
Anything not working? If yes... What???
If the unit switches on with Key in Pos 2 or ignition and powers down when removing the key, the CANbox works as expected.
If you want more, you may set the correct CAN settings in the head unit.

In this case get in contact with the seller, give him all information about your car, incl. model year and what is needed and ask for the correct Can adapter. Might be the wrong one for your car.
I ordered an extra head unit for Golf sportsvan 2014 he knows exactly my car . without can bus i have black screen i think it is right can bus maybe software problem that because i posted here
You just get information from the CAN if the CANbox could interpret the messages. If not, nothing is shown.
I´m still pretty sure that the CANbox is the wrong one or the settings in the head unit are wrong.
please poll the android car stereo out and check if the the can bus connected an if there is no short with cables, then take a photo for the can bus sticker and send it here
...and I mean to read out any error message stored on the modules.
It always can be possible that any issue on the CAN sets an error code in the BCM (Body Control Modul).
BTW: If you just connect something to the CAN, you need to make sure that the CAN is terminated.
Needs to get read out with an OBD scanner.
Could you explain this last message? How would you recommend looking at the CANBUS to determine whether a head unit is causing a short/issue versus another vehicle component/wiring issue? I'm having a lot of issues after installing a new stereo, but was having a few minor issues beforehand in the same general area of the vehicle.
Well...
If any attached system has issues and disturbs the CAN, you will have multiple issues in this CAN.
You need to connect an oscilloscope to see what is going on on the CAN and if the signals are correct. If they are not correct, you need to find the controller or device which is disturbing the communication.
As long as this has not been fixed, you may have issues also with the radio. Analyze the issue correctly and fix what you will find.
You need to get the diagram of the CAN where the Radio is attached to and then follow the diagram to narrow that down.
At least a scan for errors with a good OBD device will help to filter out what is wrong.
