I have swapped the motherboard of my Clarion unit from a version without BOSE (camera button on the front). The system works perfectly, except the camera button, which does not react. Even the AVM screen is perfect, when I switch to reverse, but without the camera button, I cannot switch to AVM mode with front camera.
I know, that in the Testmode it is possible to change the device type, like this the camera button would work. I can enter to the Clarion Testmode, but the following screen is visible, with the message: STATUS>>>STANDBY
Does anyone know, how to move on within the testmode? Shall I push the screen in specific points? Or use button combinations?
