My car (Lexus) and my iPhone X: The car detects iPhone presence, like, 50% of the time. If it does detect it, it shows me a couple of half-naked shaved guys hugging each other and begins playing "Songs of Innocence" the moment I turn the ignition on. I tried deleting this song from the iPhone, but it auto-magically restores itself somehow, as if it is in the telephone's firmware. The image of men hugging in shade is…

Bluetooth is absolute garbage, I hate it with a passion even if overall it works in 90% of cases.

Just the other day I was connecting my phone to a mobile speaker in the garden. The phone is an inch away from it. Still doesn't connect, just a spinner that times out after a minute with "connection failed".

Why does it fail? Who knows. It might work tomorrow. Or on another phone. Or when the weather is different. What on earth are two devices directly next to each other doing for 60 seconds?

I also have a few BT controlled LEDs where from an app I control brightness and color temperature. My phone is always in range, but the BT connection just doesn't sustain itself. It intermittently drops after which I need to redo the setup again on every single light.

I'm sure the reason is "low power" or "interference" but that doesn't mean anything. It's not actionable. It's fragile and unreliable tech.

Everyone in this thread who is complaining has either a Lexus or a Toyota (who owns Lexus) so it’s obviously a problem with some version of their infotainment system. The U2 thing was obviously an Apple issue. Not sure why they don’t use CarPlay but maybe some people prefer Bluetooth.

I was in a Volkswagen rental last week and the Carplay integration was a disaster. 50% of the time, attempting to play a song on spotify would crash Carplay. It would refuse to work again (or hey, crash again) until you'd left the car off for a lengthy amount of time. Presumably the car turns off the infotainment system at some point, so this is a reboot, but there was no way to reboot manually... So it would remain…

I've owned a VW for 6 years and Carplay has always worked flawlessly.

Similar thing would happen in my Toyota, the song 'Afraid' by Yellowcard would play every time I turned on the car. Realized it was playing the first song in my library. In Apple Music there is a song called 'A a a a a Very Good Song (Silent Track)' by artist Samir Mezrahi, that contains 10 minutes of silence. I added that to my library and now that song plays when I turn on my car (although this autoplay only happen…

There's an app by Apple that allows you to remove the U2 songs

Looks like that might be retired going by https://discussions.apple.com/thread/251184844 > Customers are no longer able to remove the album on their own. You will need to reach out to Apple Support directly to have the album removed

I guess this is the essence, of why I never wanted an apple device. And I bookmark this comment, in case I forget ..

I would need to ask my apple masters, if they please remove U2 from my device? No thank you.

Bluetooth is quite amazing in general. What it is capable of with extremely low energy usage is just mind blowing really. I think the main reason it gets a bad rap (e.g. vs WiFi) is that the radio link is conflated with all of the messiness of codec/protocol compatibility and features provided over said radio link. If there were standards for devices to stream audio over WiFi links, I imaging we'd see nearly similar…

I think the main problem is exactly as the article states - there no standard for how things connect to each other. If they could just make the connection standard everywhere, that would get rid of a ton of the silliness.

Try getting thousands of organizations to agree on something and then implement it successfully... The complexity of the problem far surpasses that of the technical standards themselves.

The most grating "feature" of Bluetooth is having headphones that support fancy AAC/AptX codecs, but as soon as you want to make use of its microphone it dumps the connection right back to A2DP.

A2DP doesn't support microphones. You're thinking of Headset Profile (HSP). That's the low-latency profile with mic support.

It's definitely a Lexus problem. In a ford I think it just continues playing whatever the last played song was.

I also put songs on my iphone instead of using apple music, so I suppose it could be an issue with that service although idk why it would behave way differently from playing local files.

A 25 dollar logitech wired headset with a boom is brilliant. I have people with $200+ airpods on the call and I hear their cat dog air conditioner wind spouse keyboard car and everything. But they cannot be told this - they have expensive earbuds and they can hear ME fine, so it's all great!

Boom mic is always the superior choice.

Yes. All the software / DSP processing can't help if the physics is against you.

By placing the microphone close to the mouth noises you make, you are increasing, by many orders of magnitude, the signal-to-noise ratio.

Cars and other large BT devices (like an Amazon Echo) can use multiple microphones and some fancy processing to really isolate the voice signal coming from a specific direction (relative to the device) and also cancel out surrounding noise sources.

With ear-bud systems, you can't fit in many microphones, nor can you spatially separate them enough for the software to do the job.
