I don't know that there is any such thing available with built-in Blu-ray capability.
It would be a lot easier to just buy a separate Blu-ray player and connect it directly to the television using an HDMI cable. That's what I did. If you wanted to, you could connect the audio output from the Blu-ray player to the rear AUX input on that factory unit or get a soundbar if you have the budget.
