I'm doing this from memory since it's been about four months since I actually did this.
This is for a 2005 LX. EX procedure may be slightly different.
Disconnect the negative battery cable and make sure it can't come back into contact with the negative battery terminal.
1) Remove the plastic tab (where a push button probably is for EX model) to the upper right of the radio.
2) Carefully pry off the plastic piece which surrounds the stereo. I used a thin screwdriver and sock, and slightly scraped things up. In hindsight I should have used a specialized pry tool for removing such things. I think there were four or five places where this plastic panel is clipped into place.
3) After you get the plastic panel pried off, slowly remove it. You will need to disconnect the three wire harnesses connected to the buttons / indicators on the plastic panel.
4) The plastic panel should now be out of the way. Remove the four mounting screws holding the radio in place.
5) Slowly slide the radio towards you. Disconnect the wire harness and the antenna.
6) You should be ready to install a new stereo.
As a side note, when pulling the wire harnesses apart be sure to pull from the plastic connectors and not on the wires. If you pull on the wires, they may come loose from the harnesses.
If you are hooking up an aftermarket stereo, be sure to use a wire harness to connect from the aftermarket stereo to the Pilot's harness (otherwise you'll end up having to cut off the Pilot's wire harness which isn't ideal). I'd also recommend soldering and heat shrink tubing the aftermarket stereo's wiring to the aftermarket stereo's wire harness. It takes a while longer than the crimp or electrical tape method but ensures a robust connection and no electrical shorts when done correctly.
My aftermarket stereo has a power antenna connection. This needed to be connected (the Pilot's antenna is part of the rear window and thus isn't powered) because there is a signal booster which requires power (otherwise you won't be able to tune into any AM stations and will get very poor FM reception).
I have a 2002 LX, the 2004 should be the same, and I have done this already. Gently pry the plastic trim from around the radio itself, the automatic gear shift lever may get in the may so you might want to turn the key on and take the car out of gear, if doing this remember to use your parking brake first! The interior dome light switch has a very short wiring harness, this unplugs easily to allow you to swing the plastic trim up and out of your way. Be careful because the heater assembly remains connected to this dash piece. Now that the dash is disassembled, the stereo is easy to get out, there are 4 Phillips screws that hold the radio and storage bin into the dash, they are held together with a clip in the rear of the radio. Once you remove those screws the radio comes right out and the antenna and wiring harness easily unplug from the rear of the radio.

If you have already tried to enter a code many times, and it doesn't work, do the following: 1. Disconnect the battery, 2. Connect the battery, 3. Put Radio ON 4. Enter the radio code of 4 digits, 5. That's all. If you don't have the radio code of your Honda Odyssey, have on hand its VIN, and ask your former salesperson or your former dealer.

most radio head units have tabs on the side where you need what is called radio keys to remove most times two butter knifes will do if you can see the tabs
If you are referring to the factory supplied radio, it is not a 'component' type radio. It must be removed from the dash and dis-assembled.
* Remove the ashtray and ashtray holder * Remove the radio and mounting plate screws and lower the radio and unplug the electrical connector and antenna lead then push the radio out of the dashboard

There is nothing to reset except the radio. Insert the 5 digit radio code to reset the radio and then reset the clock and presets for stations.
One might look to a Chilton manual or the car manual to learn how to remove a Honda jazz radio. The best way to have a radio removed from any car is to take it to a car audio technician and get the radio removed and or replaced.
