Sorry for any confusion I have a five series M sport 3 L diesel. The factory in the roof liner no bigger than a Matchbox I didn’t fancy paying over £500 for BMW to put it in so I had a go myself I watched a quick video on YouTube it’s took me 25 minutes I’ve saved over £500 I suggest other people have a little go there self sometimes thank you for all the replies I’ve had much appreciated it is a shame I’ll pay £28,000 for my car I’ve only had it a year on the sort of person when things start going wrong don’t know how little I just get rid of them
