    Can anyone help me to unlock my Acura Radio. I entered wrong radio code and it got locked up. Now it is not accepting the code (I got the unlock code from manual now). Someone told me to disconnect battery and try again, but it did not worked. Is there any way of clearing the lock??

Hey you guys. came here looking for a free stereo unlock code as my uk dealer wanted to charge me nearly 25 quid for the pleasure! nuts to that so... Well it turns out that if you go to the dealer that sold the car originally they keep a record of the original unit's unlock code and will give it to you gratis over the phone. that's more like it.

    So what's the code



I have this problem almost everytime I have to do it.  It's such a rare occasion.  If I remember correctly, just press and hold the key that moves you to the next number... the >>| key, I believe.  After a couple seconds it'll beep & open up (provided you have the correct code).

Kenwood Kdc-mp425 will not switch to Aux. Aux cable is connected to the back of the headunit, but no aux option is available on menu for either my ipod touch or my sirius unit. I've accessed the menu from...

Apparently, this auxiliary input only works for a Kenwood CD changer or a sirius radio connection. At least that is my conclusion after finding the same problem. Let me know if you figured anything out on this.

Radio is not coming on at all

Check the fuses. Radio fuse in fusebox (red 10A) and also inline fuses behind radio on red and yellow wire.
Otherwise seek service.
