Hi I have jaguar xf 2008 system head unit keeps on cutting off now tried looping but not worked also replaced Bluetooth module box still no luck it worked for about a week can seem to understand when the unit was replaced there was no water damage or anything on previous box aswell!
Heating cooling control remains on when system cuts off does audio sat nav and telephone connectivity goes off what happens it goes off and then comes back on within few seconds and happens constantly really is bugging me wonder if anyone could kindly help/advise
Also if there an after market system I could replace but doing do would it resolve the issue?

 

Do you have anything plugged in to it? If I leave my phone connected to the USB port, it cause the head unit to blank out.

I use a bluetooth adapter through the 3.5mm port now for streaming audio and a light port charger so I don't need to connect anything to the head unit.

 

Hi nope I don't
