I am on software version 3.3.16.981 although haven't checked for an update recently.
The DAB signal on Absolute is non existent, most of the BBC stations are OK but there are a couple of local blackspots where the signal always drops. Heart seems to be the most reliable. I am in Eastbourne, which I think some of other posters are as well so it would be interesting if they have the same issues with those stations. I also have the central display that will not hold its setting and defaults back to style 1.
I have heard it is a common issue on a range of cars with DAB and not unique to Renault or the Kadjar. I do wonder if it is the signal we have in the UK and it is better elsewhere.
