stupid me left the lights on..and the car battery drained out...then when i boosted it up..the radio prompt to security code...(which is all normal)..the code I have...but when I enter it then press "2 & RHD"..it flashs a few times...when "SAFE" still stays on....by the book..it only does that when the code is wrong...soo wat this heck it up with the radio???

 

If you want help, state what year and model car and which radio.

 

Hey i have the same problem, i have the code but when entered it does not work. the car is a 99 a4 1.8T and as far as i can tell it is a audi concert radio. thanks in advance for the help
