Okay so you guys ran into the same issue one of the civic guys ran into. You guys are using a brand new headunit from a CR-V that was never paired with a CRV so is going to what the dealership calls diagnostics mode. I provided some guidance for the civic forum guy.
On first power up you will get this screen:

Press all the buttons on the Steering wheel to verify them then press Done without entering any numbers
Press and hold Power Eject and Home all at the same time for several seconds. You will then see this screen:

On this screen Press and hold the Power button for several seconds.
You will get a screen asking about inline diag settings. Tap that to set it to complete and then tap return
You should now be at the normal startup sequence.
Power everything down and if done correctly, it will boot up normally with no diag window.
