That Hidden Code For Radio ???
So I went in to get my emisson test today, and before this a long time ago after reading a post on this forum I went into the backend of the radio [by using some form of code such as holding down 1 & 6 and press AM three times?] to mess around with the setting so my bass increased by almost 50%.
After finishing up at the test I noticed that my bass was much lower, so I am thinking that maybe it was reset
Anyhow I cant find the topic anywhere, anyone know that code?
Thanks

What struck me was that the front door bass reflex enclosure was very carefully designed all the way down to the grill that redirects medium frequencies and the ducted bass port sealed to the door. Lexus has put a lot of acoustic intelligence into even the standard audio system despite the “transistor radio” comments here ( I used to work in broadcast audio studios) . The replacement 4 inch speakers I bought had much smaller magnets and seamed to be similar quality, tarted up with glossy cones and little additional quality so I left the original in place for now after hours of experimentation. I’ll probably change them later, but I decided to focus on the electronics first.
I had hacked the Pioneer amp about 4 years ago (not recommended) to increase Bass gain and replaced the woofer for a Boston Acoustics high efficiency woofer with a cast frame. Despite my adjustments I was never happy with bass response and had the EQ set to near max with as a poor compromise to get more sub bass yet over-drive the door speakers.
Getting to the point, I researched the amplifier and came across the service mode for the Pioneer amp via the NAV system – there is a similar adjustment for the non NAV cars. Here’s what you do:
Get into the NAV diagnostics mode (covered in these forums before) - hold the Climate and Audio controls while switching the parking lights on and off 3 or 4 times. This must be done immediately after tuning the key on. The new step is:
• Once the diagnostics auto test completes, press the menu key on the touch screen, then hold the AM button for 5 second until it beeps.
• The display will now show “Audio”
• The TAPE button toggles through F, R and W for Front, Rear and Woofer. The UP DOWN button can set these from 0 to -80 dBs.
• The FM button toggles between P1, P2 and L, where P1 and P2 are equalizer frequency settings and L is the overall level from 0 to -20 dBs. I haven’t figure out what the equalizer setting do exactly.
• The setting appears to be non volatile so switching the ignition off keeps the values. I now have a system that is much closer to my preferences with the controls flat – always a good place to be. Happy tweaking.
For non NAV cars it appears that the diagnostic mode is set by pressing the CD key 3 times while holding down channel 1 or 6. Auto level or ASL must be on first. Then press the AM button for a few seconds or LW/MW button on some non US cars to get into the amplifier DSP mode. Note that I have no way to test this.
I also have no idea what happens with a DVD NAV car.
Of additional note is that the audio system has alls sort of features not used including MD, DAT, rear seat TV, rear control and adjustable length antenna depending on what FM frequency is used! These appear to be for non US markets. UK cars have a telescopic antenna.

THANKS so much mikal !! That's it Now time to see if the emission test did reset it

cool has anyone tried this on an 01+ non ML/Nav GS?

I have a 01 GS430 with ML and Non-NAV.
Done the holding of Ch1/6 and pressed DISC (3-times). The display shows P190. Pressing AM for 4 sec or longer does nothing. I can't seem to get to what you guys are describing.
I fool around with the buttons and found the following things.
1) Pressing Seek/Track UP/Down button would alternate the following display when I press the UP/Down button.
P440
GOOD
P190
GOOD
P1C6
GOOD
P360
GOOD
2) Press CH1 and get a 3 short beeps
3) When the display shows P190 pressing CH5 will provide a long beep then a display CLR
4) Press UP and display shows P360 pressing CH5 will provide a long beep then a display CLR. Press the UP again and display shows P440 and pressing CH5 will provide a long beep then a display CLR. I guess this is to clear some type of setting for P190, P360 and P440.
