I know there are a few threads on this topic but they all seem to be from 2006 and i'm hoping more information has come to light. The ASL on my 350 w/ nav doesn't seem to do anything?! Whether I'm on the freeway going 80 or doing 35 on surface streets. I do see the bars going up and down (the highest I've seen is 2 out of the 5) but there is no volume control whatsoever regardless of the number I set the volume to. My 03' gs430 had a way more noticable ASL system so i'm thinking there may be something wrong w/ my IS. Anyone come to any better conclusions about the system besides the fact that "it just sucks"?!

 

i thought u were asking for age, sex, location

 

Yea I would like to kno more info on this also

 

I feel the same about my '09 system. Probably one of those "added features" that doesnt really work...

 

Me too!

 

Mine works just fine. The bars go up and the volume does too.

NOTE: If the volume was set at 20 when your stopped and you get on the interstate going 70 and it goes to 3 bars, the volume will still be set at 20 but music will be playing louder.

***But the whole point of the system if for the sound to always sound the same, so it shouldnt be very noticeable.***

The biggest way to see if its working is to get on the interstate going 70 wiht the ASL on, then turn it off, the music will sound quieter since it will be playing at the "stopped" level.

Hope that helps.

 

BTW... If you turn it on and off while stopped or at low speeds = no difference. You have to be moving, the more "road noise" the bigger the difference.

 

It works fine for me

 

Maybe you just have good tires and produce very little road noise.

 

it works but not dramatic....

 

No thanks.

 

12/m/CA yes pls.

 

what is this asl stuff? im looost

 

Auto-Sound Leveling or something like that. Turns up the radio to compensate when the ambient/background noise goes up.

 

ahh i see. thanks for sharing the info. saves me from having to research it im gna check for this the next time im on the road/highway
