Radio Installation
Can anyone guide me on the locations of any aerial or radio module(s?) and cabling in the V40?
I had a rear-end shunt a few months ago, and ever since then I have had faulty reception on all DAB stations (but not FM!), The signal breaks up completely - on/off, second by second. It 'feels like' a loose connection somewhere between the shark fin and the radio itself. I didn't make the connection (no pun) between the shunt and the reception problem until it was too late to get it investigated under the insurance claim, so now I am hoping to trace the route myself from the aerial to the radio looking for the perceived bad joint. But, short of pulling out all the interior headlining and trim, where should I be looking?

Oh! That surprises me.
Before I start exploring, can you amplify what you mean by window "elements" (and I assume you mean the rear window)? It may become obvious once I open up, but it helps to be clear in advance just what I'm looking for/at. Also, is there any trick or pressure points for removing the trim? 'Errors' can be messy in 'trial and error'! I've pulled on the edges of the trim but it is not coming away easily (yet).

By Window Elements he means the on-glass copper strips that you see on the window
They are bonded to the inside of the window glass and the patter is a very carefully tuned antenna system, and is mostly also part of the rear window demister Check the electrical connectors to the window are on properly. You may have to remove the interior trim around the window to see the connectors.

Radio Reception
There have been a number of instances where people have destroyed their radio reception by scraping off Dealer stickers from the rear window and also from having secondary fit window tinting applied.

I removed the trim panel and checked the demister connections and the little box beside it. Everything is tight. Guess I'll need to try and trace the wiring back through the car now.

Thanks for the heads-up.
Unfortunately my Volvo dealer has let me down with electronics in the past (which is why they were not my first port of call), and the next nearest is quite some distance away, but I'll phone around anyway.

A Happy Ending
If, like me, you always want to know how a story turns out, then I am pleased to say I have an ending to my tale.
One thing I did not mention originally is that, because it was my second rear-end shunt in the space of a year, I fitted a rear-facing dashcam at the top of the rear windscreen (insurers love photo evidence). The dashcam is the 'wifi-to-smartphone' type - better than twisting your neck up to view a screen at the top of the tailgate. You've guessed it! The wifi signal was interfering with the small DAB box right next to it. Move the camera to the bottom of the windscreen, and all is well!
