Recently moved from TX to OK and along my route to work there are two places that every single time I drive them, my bluetooth connection from my phone to my truck will drop. Aside from this being really annoying, I'm curious. This is on podunk backcountry roads west of OKC. I realize the 2.4ghz band is widely used but my phone is like 2 feet from my truck console at most. That's got to be a really high level of noise to break that connection.

What could cause this?

We have the exact same problem driving on 287 just outside of Decatur. Same exact spot, every single time. The car disconnects from the phone Bluetooth.

Almost certainly interference from other sources in the same frequency band if it happens in the same place regularly. Given that Bluetooth operates in the 2.4 GHz range, my initial list of suspects would be S-band radar sites and high-power comms relays.

I've had the same exact problem in both CA & CO in particular spots. I think it has to airports. Here in CO issue is in lone tree on I-25 near the centennial airport and there's another spot here in the springs that I suspect is under the COS approach. The issue in CA was near a local FBO which I found interesting as well.
