Hey all!

Ok, I got this pre-owned '06 Honda Civic. For some reason the battery was disconected in the dealer and the radio needs the code (as everybody probably knows here) and of course I did not get the radio code.
I got the car in a Toyota dealership so they really did not know how to work with Hondas.
Anyway, I went to a Honda dealership to try to find out my code, and they told me that the radio doesn't look like a factory radio although it has the Honda symbol on it! I mean, it's a Honda radio!
The serial number doesn't have 8 numbers as the factory Honda radios, but 11!
It doesn't show an U and L but 1st followed by 4 numbers, 2nd followed by an R and 3 numbers and 3rd followed by 4 more numbers
Anyone can help me with this? I have had the car for a month now and I haven't listened to music since then!!!
Thank you!
