What do you mean? finding one in stock or that fits the murci? since I think having a Double Din is one of the best things in the interior, it can never get too old unless they stock producing them which I'm not sure that is possible anytime soon.
I ended up putting in a Kenwood DNX9190DABSC Media Receiver - awesome unit, probably overkill with the Nav as it has Apple CarPlay and Android auto included, but stock was an issue and this was what they had. Cool thing is you can put on a custom background which makes it look factory if you use a Lamborghini logo..
One thing to note, most of these type of units will struggle to open when the surround trim is put back in as the screen is so big that there is minimal clearance. I got around this by putting in the map SD card with the trim off first.
