Here's a general outline:
1. Gather your tools: You'll need a set of trim removal tools (plastic pry tools are ideal to avoid scratching the dash), a Phillips head screwdriver (possibly a Torx screwdriver depending on your radio's mounting screws), and possibly a wiring harness removal tool (though you can often disconnect them by hand).
2. Prepare the area: Remove any obstacles, such as the ashtray or cup holders, that might interfere with accessing the radio.
3. Remove the radio bezel/trim: This is the plastic trim surrounding the radio. Carefully insert your trim removal tools into the gaps between the bezel and the dashboard. Gently pry the bezel away, working your way around the perimeter. Be gentle to avoid breaking the plastic clips. There might be several clips holding it in place.
4. Disconnect the wiring harness: Once the bezel is removed, you'll see the radio unit itself. There will be a wiring harness and possibly an antenna connector connected to the back of the radio. Carefully disconnect these connectors. Some connectors might have release clips or tabs that need to be pressed to unlock them. Take pictures before disconnecting anything to help with reassembly.
5. Remove the radio mounting screws: You'll find several screws holding the radio unit to the dashboard. Unscrew these and carefully remove the radio from the dash opening.
6. Remove the CD player (if separate): In some 2002 Mustangs, the CD player might be a separate unit that is integrated with the radio head unit. If this is the case, you'll need to disconnect the connectors to the CD player itself and remove any screws that hold the player to the radio.
7. Reassembly: Reassembly is the reverse of the removal process. Make sure all the connectors are securely connected before reassembling the bezel and trim.
Important Considerations:
* Consult a repair manual: A repair manual specific to your 2002 Ford Mustang will provide detailed diagrams and instructions. This is highly recommended to avoid damaging your car's interior.
* Professional help: If you're uncomfortable working on your car's electrical system or interior, it's best to take it to a qualified mechanic or car audio installer.
* Antenna: Be careful with the antenna connector. It can be fragile.
Remember to always disconnect the negative battery terminal before starting this process and reconnect it once finished. Take your time, be gentle, and if you're unsure about any step, consult a repair manual or seek professional assistance.
