Get this and this splice the respective colored wires and you're done!
Mine was a Bose as well. I'd highly encourage you to do the swap - modern radio features are pretty neat, and you can even put in something like this if you're feeling adventurous.
According to miata.net's audio page, the head units are all pretty similar - it seems the biggest difference is determining if you need to buy either this wiring harness or this one.
Both the head unit and the harness come with instructions on which wire carries which signal, so soldering them is simply connecting A to A. Honestly, the most difficult part of the swap I found was installing the mounting sleeve in my console - the unfinished metal edges dealt me more than a few cuts due to my stubborn refusal to protect my hands.
I spent a bit of time kicking myself for not photodocumenting the head unit installation, but ah well. There's no shortage of people willing to advise on the subject.
Yes. I think this one but if in doubt use crutchfield.com.

as for radios with navigation built in. they start around $550 and some will have the ability to do apple carplay or android auto. as for satellite radio, most do not come with it BUT they have the ability to have it added easily. usually a $35 to $50 tuner which can be connected to most aftermarket stereos. then you just transfer account to new sirius tuner ID and you are good to go.

You can buy a radio from walmart or Electronic Express that are pretty reasonable. Best buy and Electronic Express can install them for you too. The downfall to changing to that set up is you lose clock control "possibly the whole LCD display above the radio" and steering wheel controls. If you don't mind that then this is a much less expensive alternative.
That shouldn't be too difficult at all. The first one I did just took an hour or two.
The stereo will come with its half of the wiring harness. You'll need to buy the other half. For some stereo manufacturer/auto manufacturer combinations, there are ready made harnesses. For all others, you'll buy the vehicles side of the harness and either solder or crimp the two together. This saves you from having to cut into the factory wiring harness. This wiring harness may fit your vehicle.
I highly recommend soldering and heat shrinking the leads. Crimp connectors can fail, and a properly soldered joint is fairly permanent. If you've never soldered before, don't worry. This is a good project to learn on and there are plenty of good videos on the subject on YouTube. I have a butane powered soldering iron that I use on simple things like this because it heats up super quick and is portable because it doesn't have a power cord to worry about.
You'll also need the dash kit that the stereo will sit in inside the dash. This one might fit your vehicle. For that head unit, you're looking for a double din installation kit.
All in all, it's a great do-it-yourself job that can make you more comfortable working on your car.
