Hoping someone can help / point me in the right direction.

I have a 2011 XJ Portfolio and after around 90 minutes the sound cuts out, along with the parking sensors, rear camera no button presses on the front screen make any noise and the navigation system says initialising.

I have replaced the battery, the front console ( with the bluetooth / dvd player & nav system in and just replaced the main amp ( DX23-19C164-BA ).

It is still doing the same thing. It resets when I turn off the engine, lock the car and leave it for 30 seconds.

Help please

 

I've moved your question from X300 to X351 forum. Members here with the same model will be able to help.

OK - development - I have tried removing & reinstalling the fuse F41 in the rear fuse box for the power amp without turning off the ignition - this restores the sound without turning off the ignition - so I'm guessing it's something to do with the rear amp but can anyone suggest how to test the amp or what might cause it to shut down?
