So I was installing my door speakers on my 2005 Acura tl with navi. I unplugged negative side on my battery n installed my front driver side door speaker. I plug my battery back up n turn my car on to test the speaker. My radio doesn't work, none of the buttons am/fm disc/tape or any of the other radio buttons work. I don't know what I did. Has anyone else had this problem?

 

Push the volume knob in (audio power button).

Your Sub-display (information area on top of center vents) will prompt for a code.

Type in your radio code using the preset buttons.

You can find the code usually in your glovebox, or inside your car manual card slot

 

If you're close I'll fix it for you for a couple hundred.....

 

Thank you so much guitarplayer. It works now, you saved me a lot of hassle n money.
