I'm not sure if that's how you spell it, but the Mazda technician said "tuner amperer".
In any case, I recently went to a Mazda dealer because there was radio static every time I hit the brake. This was most noticeable with stations with a weak signal. This is the question: Active brake lights interfere with radio station on ‘16 Mazda CX-5?
The Mazda dealer blamed the antenna, even though I had a hunch that it wasn't the issue. It turns out that it wasn't the antenna.
They're still diagnosing the issue, but the Mazda technician says it could be the "tuner amperer". He says it's a mass of cables in the car. According to the dealer, this part costs over USD$1,000.
What is this so-called "tuner amperer" and could that be the issue?
