2012 Jaguar XF X250 Luxury Sportbrake

[72773719]

Hello guys, hope all of you are well.

I've just picked up a new (to me) 2012 Jaguar XF X250 Luxury Sportbrake this week. Im liking it so far, however it has a few issues which I would like to ask for assistance/guidance from fellow owners and members.

Issues :
1) Radio/audio button is greyed out, there is no sound at all
2) Satnav does not work, just stays on black screen and says initialising
3) Reverse camera does not load either, just stays on black screen. Parking sensors do work though, just not the camera.

I have scanned using an Autel AP200, and have attached the report for the fault codes for you guys to take a look at and offer any suggestions.

Also, the car has covered 135000 miles, and has never had a Cambelt change. When should I look into doing this?

Thanks for taking the time to read my post, I look forward to your responses.
