Having had a few issues with my main computer screen, not recognising sd card, failing to communicate with my phone, yesterday i hopped into the car for nothing other than reverse camera to work on the screen, other than that just a black screen, tried turning engine off back on again etc but nothing, was due to go on a long journey on the motorway with a car full of children so rang my landrover dealer for some assurance that all would be ok, they told me to ring land rover asst who sent someone out about an hour later, a really nice helpful guy who jumped in and hey presto it was working, albeit it was very slow to load and continues to be so, so thinking the system must have a glitch. The car is booked in for some other bits and bobs so this is added to the list, anyone else experienced this?
