2002 L322 V8 Vogue. Unfortunately I had to have the vehicle jump started (due to alternator failure). New alternator now fitted and all is fine but the radio/cd/satnav display has gone! Radio/cd are working fine, but no display. I have tried fuse 49 out/in after 15 minutes but still no joy. Everything in the rear n/s compartment looks ok. Any ideas how I can get the display back? Thanks.
