NG4 New Firmware R42.01

Sounds like it's getting hot and shutting down from heat.

Is your heating on?

No never really have the heater fans going to be honest mainly rely on the heated seats, just thinking as well it has only started to do this after the update, played cds fine beforehand

I would try the update disc again, but it probably won't actually do anything as it will detect it is not a newer version.

If that is the case, I would have a trip to the dealer that supplied the disc, and explain what is happening afte the update. I have a feeling however that they will want some of your hard earned to sort it out. It might be the only real option you have.

Thanks for the responses, I have tried three times to reinstall the disc all saying successfully installed updates. Went for a journey yesterday and tried a couple of different cds (haven't used the CD player for a month or so) and it played them absolutely fine. I struggle to believe that three cds won't work in it but it's playing now so happy days.

happy days, fingers crossed no future issues

There is a map update for NG4!
It's derived from maps produced for BMW, but doesn't include 3D pictures for landmarks and I noticed that names are clipped before special characters like ë but the map information apparently is from 2017.

I've installed it yesterday and so far it works OK.

I might give it a go. I think mine is on 2016-2 maps.
