Hello. I have a 2003 TL and the headunit is asking for the code. I am the cars first owner so I have the correct radio code and it has worked before. However it says error when I enter it. A buddy of mine knew to hold down the 1 and 6 button simultaneously and the radio gave two codes

U3007
L2803

Anyone know what these codes mean and what I need to do? Any help is appreciated.

 

Find an underground garage where there is no radio signal. Punch in code and voila

 

Those codes you have can be used to retrieve the radio 5 digit code from a dealer or Acura direct. I just too had the problem where my radio would not accept the code even thought it was correct. What i had to do was disconnect the radio antenna which is located at the top of rear windshield under a plastic cover. I disconnected that and tried the code and it accepted and then i reconnected the antenna.
