I didn't even know "salt neutralizer" was a thing. This is just Guyeon Foam. Get the car wet, spray it with the Foam, let it soak in for a couple of minutes, hose it off. Then you wash normally.
Like I said, this is South Carolina. I'm 53 years old, and this year is literally the first time...
It was fun in my Plymouth to hit 85, and then the needle would bounce off of the peg. Then I kept going, and it would bounce a little lower, a little lower, then finally rest on the peg!
I did the math, I think I got up to like 115 in that POS.
So check this out, if you bought it used, it is quite possible that sometime in the past, one of those Buy Here Pay Here shady car lots put a fake OBD-II connector on your car. Yes, the do they because they install interlocks that won't let the car start if you miss a car payment.

I have front and rear cameras hardwired. I bought two Viofo A119 Mini 2's, because running a wire from the front to the back was too much of a chore in this exact car.
I used the Dongar hard wire adapters, generic for the rear, and 10 pin Type E for the front
I can't specifically say for the CX-5, but the C panel speakers for the CX-9 (which are probably the same thing) mount from the rear. Only the speaker grille itself mounts from the front.
If the wires were pulled, they may have been pulled for a reason.
You can try a radio from a junkyard, or you could go aftermarket. Either would (should) work. If they don't work, something electrical is wrong, and a rabbit hole is on your future.
All the radio needs to trigger is a 12V signal. Just tap at the reverse bulb using the red wire that every reverse camera has built-in to the RCA video signal cable.
Brake replacement has nothing to do with mileage, and everything to do with use.
If you have a Miata that you hammer on at Road Atlanta or Sears Point every Saturday, you're going to go through a set every 250 laps, or 625 miles.
If you have a Mazda5 that you use for inner city Uber driving...
55/45 and 50/50 really ain't that big of a difference. But if you want to mix yours a little strong, meh. You still come out cheaper than buying pre-mix.
