Same thing happened to me on my 2016 Kadjar– it’s happened three times – the first time everything was dead -sat nav and speedo – took it to the dealer and they took a week to fix it. The second time, just the sat nav was dead – took it to the dealer again and they fixed it in a couple of hours – told me they did a software update. Well here I am about two weeks later and its dead yet again. I’m now not so sure they did a software update – maybe just some sort of reset. I’ve tried the long press of the power button but no joy
Not sure if it’s worth disconnecting the battery to ‘hard’ reset it or will I cause more problems?
Is this a common problem?
An update to this post - had the car booked in but before I could get to the dealer I had a flat battery so needed to fit a new one. This obviously required me to disconnect the old battery - the net result is that the sat nav display is now working - so a 'hard' power reset seemed to fix it.
I'm still faced with the worry that there is still a potential fault that could re-occur (and with the warranty end date fast approaching !) - the local Renault garage are saying they can't do anything unless its 'faulty' when I take it in.
