Thanks for the replies. Its been back to the dealer who have done a "software update" but this hasn't cured it. Both screens turned themselves off again, this time for about 30 mins on the motorway leaving us with no speedo, sat nav, phone connect, fuel gauge etc. Very dangerous and illegal so we have decided to reject the car and return it to the dealer. They have offered to order us a new car but also warned us that there has been other E Paces and Land Rover Discovery and Evoques with the same issue. They told us the new car could have the same problem! So it would appear JLR have a gremlin in their software which they are unable to fix and are still manufacturing the vehicles! I'm shocked that this may be the case
