Radio removal

Step one:
Take out the glove compartment, push upper clips inwards, let it drop out, then pull bottom.
Take out coin holder, pull at bottom it clicks out.
Take out ashtray.
Take out small panel at passenger feet attached to middle console, just pull it from the farthest point towards yourself.

Step two:
Screw out the one screw that you can see in the coin holder compartment.
In the ashtray compartment screw out the two screws at the top, then unscrew the screw that is the farthest in the middle.

Clip out the large bottom dashboard panel working from the sides towards the middle, be careful not to damage the wiring from ashtray light and cigarette lighter socket, the metal frame from ashtray can slide through the panel and you can leave it hanging or you can remove the light and remove the whole frame, disconnect the wiring from the cigarette lighter socket.

Step three:
bring your gear shifter in lowest position by removing the little plate and pushing prying in it with a screwdriver or something and lowering the shifter.
Loosen panel at steering wheel, don’t remove it just loosen it, be careful not to damage the wiring from the humidity/temperature sensor.
Take out the two screws, that are visible through the opening where the ashtray was, which attaches the radio casing to the rest of the dashboard.
Pry the panel loose where the radio and the emergency signal button are sitting in, detach the connector from the wiring of the emergency signal button and the radio.
The radio is being held in place by four bolts. You will need an adaptor from honda wiring to ISO or to the brand of radio or combination, you can also solder or crimp the wiring to the connector that probably has been delivered with your aftermarket radio.
To tidy things up you will also need another facia or trim plate for honda stream to double DIN which can be bought on amazon or aliexpress or ordered through your local dealer/ radio installer. Or you can just leave it out.
I´ve connected the wiring from the honda to the iso connecter that was delivered according to the following table:
