01 Acura CL radio code

I bought a CL that was dismantled from an auction and I need the radio code. I was told that the radio # could be displayed by holding the 1 and 6 presets and then turning the radio on. two series of #s come up U3000 L7074. Can you get the code from this or do I have to take the radio out again? VIN # 19UYA426X1A021346
