That's what I"m doing. 5 then turn it on. I have the bose stereo with the center button. What am I missing?

 

ARe you still holding 5 while you turn the radio on?

 

Yup

 

I don't think I could tell if mine got any better or not. I just use the regular buttons and it sounds great.

 

only for symphony radios

and here's the directions
here is the trick to unlocking the "secret EQ"

To access the EQ all you have to do is turn off your car and remove the key. Then hold down the number '5' on your CD changer/Radio preset control and power on the head unit.

You will see '55555555' if your radio is in stock form. These numbers represent 4 EQ settings each for front and back. They are, in order from left to right (courtesy of LCP on the AudiWorld forums):

1. Front low bass
2. Front mid bass
3. Front midrange
4. Front treble
5. Rear low bass
6. Rear mid bass
7. Rear midrange
8. Rear treble

To adjust the settings, use your volume **** to change the flashing digit to a value from 1 to 9 (1 being the lowest level, 9 being the highest) and press P.SCAN to go to the next digit. When you get to the end it will wrap back to the first digit.

 

Ok, my question still stands. I turn the radio off, hold the number 5 while turning it back on. NOthing. It just turns on. That's my problem.

 

Well I don't know what to tell you. I guess you'll have to live without it. No biggie.

 

I don;t think my 02' has it either. It is a Bose Symphony system but nothing comes up when I follow the instructions. Oh well. No biggie

 

Has anyone tried using the popular set up that was referenced above? If I could get mine to sound even better, I would be amazed. The Bose Symphony has to be the best stock stereo system I have had. I've had people comment on it when they ride in my car too. Only thing I would change is maybe adding a 10 inch sub and that's it.

 

Dont 98-99 have concert radio and 99.5+ have symphony radios?It might only be a 99.5-01 option for symphony radios.
