One-hundred and eighty media credentials were issued for the trial for news organizations from across the country, including Al-Jazeera America, Fox News, The Associated Press and CBS.
More TV networks are expected to arrive once a jury has been seated.
No decision has been made yet on the media motion to release Dunn's jailhouse recordings, but a special magistrate, Judge John Sampson, has been appointed to review the motion and make a decision. There's no word yet on when that hearing will take place.
On Friday, officials began accepting names for a lottery for the few seats available to the public for the trial. The public will not be allowed to watch jury selection.
Members of the public who want to attend must enter a lottery the day before they wish to attend. They must re-enter that lottery every time they wish to attend.
Applications for the public lottery are accepted online at MichaelDunnTrial.com or at the Prime F. Osborn III Convention Center between 6 a.m. and 4:30 p.m. Monday through Friday.
Dunn initially told police that he asked Davis and three other teens, who were in an SUV parked next to him at the Gate station on Southside Boulevard and Baymeadows Road, to turn down their music. Dunn said he heard threats from the teens and saw a gun in their car.
He said he feared for his safety and that's why he grabbed his gun and fired into the vehicle.
Police said they found no gun inside the teens' vehicle and that Dunn fired his gun eight or nine times.
Dunn has been charged with first-degree murder in Davis' death and also faces three counts of attempted first-degree murder for shooting at the three others in the vehicle. He has pleaded not guilty.
Dunn has since written a letter saying the case "has never been about loud music."
After the shooting, Dunn's original attorney, Robin Lemonidis, told CNN that Dunn was reacting to what he said was a gun being drawn.
"When all the evidence has been fleshed out, I believe that it will be extremely clear that Mr. Dunn acted as any responsible firearm owner would have under the same circumstances," Lemonidis said at the time.
Dunn's current attorney is Cory Strolla.
Family, friends of victims demonstrate outside courthouse; trial brings extra traffic to downtown
There was a small, quiet demonstration in front of the Duval County Courthouse on Monday morning by family members and friends of people who have been killed in Jacksonville in recent months.
The victims represented were Amber Bass, Michael England and Jillian Berrios. Loved ones say they were killed senselessly.
"We are just a big family and we are here to show support for all of the families that have to go through this," said Robin Lezcano, Bass' sister.
They held signs outside of the courthouse as Davis' family entered the courtroom. They said they wanted to show their support to the Davis family but also bring attention to their cause, which is finding the person responsible for their loved ones' deaths.
"There's been people yelling. People think we should be a little more rambunctious than we are," demonstrator Melissa Blount said. "But we are looking for people to speak up. We want people to tell. They know who is doing this."
