Hi all hope this is in the right place it’s my first post
Admin move if not correct please
Right got the usual random on/off problem with my HU 850 I’ve been told it’s not practical to repair it and the prices of secondhand ones I just wouldn’t pay
The CD works fine all day long but not the radio so I do have a new old stock Sony player.
Thing is nobody seems to either want to fit or can’t fit another stereo the Sony I have is a WX9800T with a 16 pin plug and 6 RCA for audio out and aerial

Got lots of questions before I go ahead and try myself here goes:-

What cables would I need? I’m thinking Volvo to iso and iso to Sony plus RCA to din for the audio

How would I connect the two din plugs on the Volvo to a new stereo?
What are the two din plugs on the Volvo actually for?

Should I just leave it altogether and just use the CD player.
The car is a V70 2005 D5 btw
Thanks
