I have a 2010 Acura rdx turbo, we went to a drive in movie and the battery died making the audio need a code. The salesman never gave us the card with a pin on it. The manual states its a 5 number code so i went online and got 2 5 digit codes for my vehicle. When i go to put them in i push the 4th digit and it says invalid pin, so im confused at where to go next........ any help

 

Oh sad to hear your story. But strange how can you go online in the middle of your journey. Was the condition too bad to move on further. I guess the manual asked for 5 code and you typed 25. There might be an error.

 

The numbers you got were for the radio serial number. You can go to the Acura web site and find the place where they will give you the radio code.

You have to enter the VIN, your home phone number and zip code (hope Acura has you registered - if not I presume you will have to go to a dealer), and the serial number that you got from the radio.

The system will respond with your 5 digit radio code.

BTW the numbers that you got from the radio were they in the format:

U nnnn
L nnnn

If so, that is the upper and lower 4 digit numbers of the radio which is actually just the 8 digits.

 

Did you get reason of above problem?, I want to know for knowledge.

 

The system will respond with your 5 digit radio code.

 

I changed the battery in my 2000 TL and had the same issue. Stupid Bose system. Junk! cant wait to rip it out and throw it off a bridge. Anyway I had to pull the stereo out to get the serial number off the radio.On the 2000 if you pull the fake wood grain piece off the passenger side of the console you will see a sticker on the side of the radio. Thats the serial number dont waste your time taking everything apart. I did just to make sure. Call the dealer ad give them that serial number and they will give you the code. I hate Bose. No highs no lows must be bose. Junk!

 

After disconnecting my battery I also had the radio lock up. I got a working radio code here:
