I have a 2000 accord coupe, with the double din opening.
Right now I installed just my HU with the previously installed single din adapter. I'm waiting for a solution to add the in dash changer and then I'll work on putting that in as well.
I ordered the factory brackets that hold the facttory double din radio, maybe those will somehow hold the 2 single dins in place, I dunno. didnt cost much though like $6. They'll be coming in, in like 10 days or so.
fastball thanks for your help bro!
