My buddy jsut got a 2nd gen TL and his battey died and he doesn't have the code card to put into his stereo. THe dealership said they would give him the code, but they need the stereo's serial number and the only way to get to it is by removing the unit. Does anyone have a DIY on removal of the unit?? I searched and found nothing. HELPP

Try this link, I've done my HD radio w/ this too.

 

The radio code should be on a sticker somewhere in the truck of the car. I just noticed mine there a few days ago.

 

Some cars have stickers while others don't. And they are sometimes in other locations such as the side of the glove box or inside a fuse box.

 

I was lucky....the original owner kept the radio card in the black pouch with the owner's manual.

You can also try to retrieve the radio code here: https://radio-navicode.acura.com/

It says you can retrieve the serial from a sticker in the glove box (ignore the Anti-Theft card):


OR
for '01s and later, you can retrieve it from the display:

 

mine is inside the sunglass holder

 

Any one ever figure out what to do if the code on the ard and the one Acura gives you do not work?
