Audio over USB on modern head units

>>17103683
It's a computer bruh. The radio is a computer, the phone sends a digital signal(waveform) over the wires that the radio then reads and turns into an analog signal from the data that it got from the phone.

rotational velocidensity or some shit

Yeah, and what's that called? What spec or branding is that advertised as? How do you know if you're buying a head unit that supports this feature?

This is seriously probably the worst advertised feature I've ever come across in car stereos.

Incidentally, holy shit are car stereos ever ugly these days. Even worse, the amount of completely fabricated market striation is insane. It's 2017, yet you don't get automatic dimming with the headlights on the base model Kenwoods and (I think) Pioneers. WTF.

USB in.

Been a while waiting for head unit thread.

Opinions on clarion fz102E?

>USB in.

I don't believe that's correct. I've used plenty of car stereos that could read USB thumb drives, or index the contents of a phone. But I've never before used a head unit that could actually stream the audio being produced by the phone, over USB.

Coming from an audiophile, I believe that head unit has an built-in DAC(digital-to-analog-converter) that took digital signal from your phone thru usb OTG and convertes it into analog signal, then amplified it and fed them to the speakers. Have the exact model name?

Pic name.

Kenwood KDC-BT365U.

I'm becoming convinced that this is part of AOA v2.

I have a bunch of portable usb-dac amplifiers that I gotta feed them thru the phone usb cable to listen to music, so I think your head unit actually works the same way

You seem to be overthinking this.

The phone knows when to send its audio through its onboard speaker(s) versus headphones plugged into the audio jack versus a USB/-C/Lightning® peripheral, based on what the phone is connected to.

Android devices support external USB digital-to-analogue converters (sound cards) just like desktop PC's do. Thus, your phone handled connecting to your head unit in the same manner as plugging in headphones.

>You seem to be overthinking this.

I'm starting to think you people are literally retarded.

I've gotten nothing but dumb, vague, pontificating comments that are nothing more than conjecture and painfully obvious concepts (e.g. a DAC is involved, yeah, duh).

You're all completely useless, but I answered my own question: it's AOA v2.

Idiots.

From the specs, your head unit can receive digital signal from its usb port, and android can send the signal out on its usb port (iphone can do the same thing fyi), so it basically what happened lol

Thanks for coming by and cluttering up the board, you tech-illiterate shitstain.

>dac is dumb
I might not knowing about the aoa v2 concept, but I was saying that there must be a DAC unit inside it taking pure digital signal from the phone, not a single bit of analog go through it. And seriously AOA not gonna work without a DAC unit on the other end.

Dunno about the 102, but the FZ502E is a fantastic unit.
Only downside is all the menu sound type features have to be adjusted on the remote, but it makes for a streamlined minimalist display.

On a side note, I'm contemplating the FZ102 for an old BMW, as I reckon the display matches the factory red/orange gauges nicely.

thanks.
I'm considering for same reason but for mr2
