2019 Mazda Mazda3 — wireless CarPlay drops at the same intersection

Wireless CarPlay is reliable almost everywhere but disconnects at the same intersection on my commute. Does consistent location point strongly to RF interference, and what would you test to confirm?

Don't overfit one forum story to your car. If it still isn't clear on the 2019 Mazda Mazda3, a specialist hour can be cheaper than another round of parts. I'd do that before spending real money. Any freeze-frame data saved? I'm in no rush to be a hero on it.

Yes, with one caveat: A second data point from another 2019 Mazda Mazda3 owner helps more than a generic diagnosis. That's where I'd start. This is from a 2019 Mazda Mazda3 in Chicago. Learned this the expensive way on a previous car. Might be overthinking it, but I'd rather overthink than overspend.

Quick add on that: On the 2019 Mazda Mazda3 in Chicago, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “wireless carplay drops at the same intersection,” that was the fork that mattered for me. That's the sequence I'd use. Wrote this up on my lunch break.

I parked the 2019 Mazda Mazda3 and wrote down what I already tested so I'm not repeating myself. Wrote this up on my lunch break.

Write down what you already tried. A second data point from another 2019 Mazda Mazda3 owner helps more than a generic diagnosis. I'd do that before spending real money. A shop burned me once by skipping that step. If this is nothing, great. I want that in data.

Thanks — that narrowed it. I'm going to try the simpler check on the 2019 Mazda Mazda3 first. If the story changes I'll post the new data.
