As you're having multiple issues with the infotainment system, then it's likely to be water damage in the boot.

However its worth checking the boot components have all their cables fully inserted into their respective sockets incase one has vibrated out 

Thanks Justin for that, I will check and hope that is all it is Discovery 3.9

Mine did this once after I first brought it. I checked in the rear for water or a loose plug and all seemed ok, so I checked in the owners manual for the fuses and pulled 2 fuses relating to the stereo system (cant remember what 2 now). I left them out for a few minutes and put them back, and it was all ok again after that.

Dont wish to tempt fate but it has worked fine since. Might be worth a go. Reformed

Cheers I will try anything, Thanks again for the reply Discovery 3.9
