Does the volume reset every time you turn it off? Current one i have volume goes down every time I turn off car

That I am aware of the volume is totally controlled by the setting of the volume on my iPhone and the volume of my car system. The Aston has no affect on either of these; nor, that I am aware of does it even understand volume. Keep in mind that the primary consideration is the volume of your bluetooth sound source. Every time I turn my car on the Aston powers up and connects to my iPhone. If I tap the "play" button on the Aston then my music comes through just the same as it was the last time I used it unless I have reduced deliberately the volume on my iPhone. I hope that this helps.

is there a on/off button or always on when power is connected? supports AAC?

Hello Kenneth Thanks for ask questions, Please see my reply as below, Hope can help you. 1. There isn't on/off button, always on when power connected (current consumption very low), Basically, The unit will auto power on and auto reconnect paired Bluetooth device (in case cannot auto reconnect paired device,Just short press Play/Pause button ,the unit will reconnect paired device,No need plug out/in USB. 2. Yeah, SoundTek A2 support AAC ,AptX ,AptX low latency and SBC decoder, BTW,We have another model called SoundTek A1 which support AAC and SBC decoder, Both A1 and A2 using CSR Bluetooth chipset(Qualcomm) and using Texas Instruments's high performance audio line driver to ensure best audio quality. 3, And both A1 A2 build in power isolator module，Which is 100% solved ground looping noise(Hum/Buzz noise），No need add extra ground looping noise isolator any more, BTW, Usually,The extra ground looping noise isolator connected on 3.5mm Aux ,That will cut low frequency a lot(50Hz -150Hz will cut a lot, not so good), Aston SoundTek A1 A2 will not cut low frequency, Provide very high quality audio signal to car stereo(20Hz -20KHz +/-0.5dB ; Signal to noise ratio up to 95dB; THD+N ratio <0.04%(20Hz-20KHz);THD+N ratio <0.007%@200Hz.

Once connected, does the phone call/streamed music come through the car speakers?

Yes, just make sure the audio input source of your car switched to Aux In mode (in order to get best audio , BTW,it is recommend to adjust the phone volume and receiver volume to max(in music/phone call/voice assistant mode) ,then adjust car volume to right level, Thanks for ask question.
