volume goes down when braking/stopped

[vpcommo]

i just had my stereo installed and when i slow down and come to a stop, the volume goes down softer than it was when i am driving, and then when i pick up speed again it goes up, but the volume on the cd player stays the same, but is definately a lot softer when stopped and slowing down. does anyone have any ideas of what it could be and how i could fix it?

The VZ's have a thing built in that when you slow down the stereo turns down, but you can turn it off in the dash menu

Not sure if any other models do it

[vpcommo]

jb hifi did it, ive done it myself on all my other cars but got it done by them this time and its gone like this...

[Tasmaniak]

which headunit mate?

[=bullet40=]

haha that got me when i got my vz stereo installed ...go into the dash menu and turn off the "speed dependant volume" option,(i thinks its called that...similar any way) and im pretty sure other models do have that option...?...

[vpcommo]

its a pioneer deh-p800 bluetooth one, is the menu to turn it off on the cd player or on the car?

First problem, using JB Hi-Fi to install anything.

I don't think that the speed dependent volume would work on an aftermarket H/U, but hey can't hurt to try. Its on the dash menu, hold down the trip buttons when starting the car, can't remember which buttons.

Welcome to Pioneer It uses an Automatic Sound Leveller. Basically, using the microphone for the Bluetooth, the headunit "listens" to the noise in the car that is not coming from the speakers. If it's loud, then it turns up the volume a bit....when it's quiet again, it lowers the volume....I bet if you sit there idling and started clapping your hands loudly, the volume would rise up....try not to do this at the traffic lights though.

Use the multi-control button and select in the menu setting "ASL"

Press the button again and it will switch it off. Also, pushing it to the right or left will select High, Mid or Low control of the ASL.

JB HiFi didn't screw up.

A VR Commodore doesn't have Speed Dependant Volume

The ASL microphone is actually inside the unit, not the bluetooth microphone.

So for those moments that you feel like singing like a drunken monkey to your favourite song, the H/U will try and drown that ungodly noise by raising the volume, ingenious. Bless you Pioneer .

It actually pics up certain frequencies so it only really works with road/wind noise. Loud talking or making heaps of noise doesn't seem to affect them

[Tasmaniak]

I found a good old clap of the hands will affect them.....and I was always under the impression when the mic was plugged in, that was the mic it uses. heh, learn something new everyday don't ya?

Thanks StoneX

I've yelled and screamed at them and never noticed any change, so I assumed it must just be certain frequency noise it would react to.

That function has been around for about 10 years in different models, long before Bluetooth was out. There's a small microphone on the top side of the circuit board which picks up the ambient noise.

LOL, someone had problems with their system
