Instrument Panel Lights

What is your question?

Last weekend I replaced the original radio in my son's 4Runner. When completed, I noticed that the airbag light would not stop blinking and the dashboard (speedometer, etc.) lights were not working. I did not notice the warning included with the installation directions, but, now understand that the airbag must be reset by the dealer. Is the dashboard light issue associated with the airbag warning? Or, is there an unrelated cause? Is this a dealer fix only situation? Thanks.
