If i use this in the car will i get the high pitched electric buzz while charging?

High pitch noise when charging but not when unplugged

Do i need to turn it on and off when not in vehicle?

Hello! This Bluetooth receiver will automatically turn off when not pairing in 5 minutes. And its Bluetooth signal range is 33 feet. So if you leave this product in car, and take your phone away over 33 feet. It will automatically shut down after 5 minutes because of no Bluetooth device connected. However, in daily use, you may turn it on/off as you like or according the real situation. Hope this answer could help! Thank you!

Is it possible to disable the voice that says "maximum volume"?

No, that is built in software.This is a simple device.
