I removed the 2006 era DVD player, complete with DVD stuck in it since 2010, the extra XM radio box, the extra nav box, 2 antennas, the remote alarm/starter that had no remaining working remotes and all its extra boxes from under the dash:
This is actually the second alarm in the van, it seems to be cheaper to buy a whole new set up instead of just the remotes. I think I used the remote start feature like once, ever. So I switched back to the stock Ford remotes which are all over eBay for $12 each, and will probably be much more reliable.
I installed a Sony XAV-XAV100 receiver, this does only radio, USB, bluetooth and CarPlay, so no moving parts. It was also tiny compared to the old DVD receiver, so much easier to install. It seems to play everything I've put on a USB stick so far, and as a plus the UI seems to be designed for adults, it doesn't flash or pulse, just a few simple icons.
And finally, a keypad to unlock the van, installed inside the passenger windshield:
I had one of the Ford keypads installed, but it wasn't that reliable after a few years, we'll see if this one is better. The price was right, $67 at amazon
