Have recently bought a XJ X351 2010, which has no entertainment or sat nav working. The red light below the on/off button does not light up, but when you press it it does come up with entertainment off, or blank when it is on, but nothing. I replaced the head unit, but all exactly the same. Queried the fuse, but the online Haynes manual doesn't help me with the location. Any ideas?
