Is there a way to change the ASL sensitivity on 2006 models having Type 1 displays (cars having Nav system)? This appears to be an option on Type 2 displays (DSP) but not on Type 1 displays.
Does anyone know the answer to this question. I would like the ASL to be a little louder when driving at highway speeds. Thanks, ---Kent

It automatically adjusts the volume of the audio system depending on vehicle speed. So you set the volume, and you don't need to raise it when on the highway, and when you slow down it stays at the same volume you set it, instead of manually flicking with it now.

<div class='quotetop'>QUOTE(usbseawolf2000 @ Apr 5 2006, 04:20 PM) [snapback]235540[/snapback]</div> I have a Prius 06 without nav and I see a High/medium/Low from the DSP selection but didn't know what it did. I have the treble all the way up, and the base all the way down and still cant hear the vocals because of the booming base - is there a fix to this somewhere?
<div class='quotetop'>QUOTE(ARiddle @ Apr 5 2006, 05:17 PM) [snapback]235573[/snapback]</div> Try cutting a bit of treble and adding a couple clicks of mids. That's closer to the vocal range.

There is also a Type 3 display which has the older appearance (look for a 3D effect in the Consumption screen.) I believe Type 3 was the early production of 2006s. Type 1 with nav has the ASL button. Type 2 has a DSP button. Type 3, I do not know.
To answer your question... No, there is no way to adjust the sensitivity level. This has annoyed me too, but not to the point of contacting my dealer. According to the tech manual, this is an adjustment made by the vehicle's speed. Not by the actual background noise as you would think. There is nothing listed as far as an adjustable parameter either. Basically, ithe manual says to check the speed input at the radio and if it's good there, replace the radio. As far as I can tell, my volume level does not increase at all as I increase speed. Anyone else?

Road noise increases, and music goes up with it. Look at the little set of colored bars the the right/below the ASL button. You'll see the "graph" extends as the ASL volume increases. So the screen says it's doing the job. Whether you hear the difference is questionable. I'll throw my SPL (sound-pressure-level, or dB) meter in the car and test in a day or so. Putting the meter against a speaker while in motion should show a difference. The meter will "hear" the road noise too, but if it's right at a speaker, most of the change should be in the audio. Now the question is to find some fairly constant audio that doesn't have normal musical dynamics. (The best test is with a constant-level source that doesn't have loud and soft parts.) I'll burn a pink-noise CD.
<div class='quotetop'>QUOTE(unruhly @ Apr 6 2006, 12:27 PM) [snapback]235832[/snapback]</div> Mine does (11/05 build 2006 model with NAV). If I am driving fast (say 50 mph or higher) and go to the audio screen and turn it off, the volume drops a lot. My 2001 Audi A6 had a similar feature with a better implementation. There was a sensitivity setting. If you put it on the maximum setting, it would turn the sound way up even at 30 mph. At minimum setting, the effect was very small even at 80 mph. - Tom
<div class='quotetop'>QUOTE(Tom_06 @ Apr 6 2006, 12:39 PM) [snapback]235842[/snapback]</div> My car is exact same build so I must have a bad radio 'cause it doesn't make any diff when on or off. Thanks for the feedback Tom!!!
<div class='quotetop'>QUOTE(unruhly @ Apr 6 2006, 12:44 PM) [snapback]235844[/snapback]</div> Glad to help. Additional info: JBL sound system and the volume was on 25 when I tried it. This was this past Friday. - Tom
<div class='quotetop'>QUOTE(Rick Auricchio @ Apr 6 2006, 08:39 AM) [snapback]235814[/snapback]</div> I believe Type 3 is on '06es that don't come with the Backup Camera. It's like the '04, '05 screen.
I've decided not to bother with the SPL meter test. You can see the "number of bars" that ASL bumps the sound. The first bump happens at 25mph, and I haven't been beyond about 40mph today to look further. But I can definitely hear a drop in volume if I turn off ASL, even below 40mph.
<div class='quotetop'>QUOTE(Rick Auricchio @ Apr 6 2006, 07:21 PM) [snapback]236030[/snapback]</div> Thanks Rick! I tried this yesterday quite a few times. Immediately after pushing the ASL button to OFF, the sound level significantly decreases to a fairly low level. After about 1 to 1.5 seconds, it returns to the previous level. It doesn't do anything when I turn ASL back ON. When you turn yours off, does it drop in volume and stay at that level?
Good morning I just found this thread while looking at another ASL thread and have a question. Is it possible to adjust the speed settings in setup mode for the ASL? Meaning I would like ASL to be at 0 when at 35 MPH or under and at maximum when at 70 MPH or above. The system just reacts to slowly in the default configuration to do you a whole lot of good. I was hoping the default speeds could be adjusted in the hidden Setup Mode. Thanks for the help. Later, Barr
