I bought form this store
https://www.aliexpress.com/store/136738
They don't sell the same one as I bought since that was over 4 years ago but this is probably the closest thing
https://www.aliexpress.com/item/4001196862190.html and it plays CDs/DVDs.
There are many sellers that still sell a CD playing unit but not so much anymore.
Installation is pretty much plug and play although I did have to route a new mic and GPS antenna, not a big deal considering all the benefits.
1DIN and 2DIN is pretty much not a thing anymore on new cars since the radio sits in a proprietary holder, not like the old days unfortunately.
If you want to buy a frame that let's you put a 1DIN or 2DIN radio you're looking at half the cost of a whole new unit anyway so what's the point?
