With the said, here are some potential steps you can consider, but please note that it may not be a straightforward process:
1. Research Compatibility:
- Check if there's a specific aftermarket radio that is compatible with your 2005 Ford Explorer and allows for the integration of your factory DVD player.
2. Obtain the Right Wiring Harness:
- You may need a special wiring harness adapter that connects the new radio to your vehicle's electrical system while maintaining the connection to the DVD player.
3. Remove Factory Radio:
- Following the vehicle's service manual, remove the stock radio unit carefully to avoid damaging any wires or connections.
4. Install Wiring Adapter:
- Connect the wiring adapter harness in between the new radio and your vehicle's wiring system.
5. Connect DVD Player:
- If supported by the new radio and wiring harness, connect the factory DVD player to the appropriate terminals.
6. Test and Verify:
- Perform basic testing to ensure the radio and DVD player are functioning correctly together with all of their features.
7. Secure the Radio:
- Securely mount the new radio according to the manufacturer's guidelines.
8. Check Integration:
- After installation, verify if all aspects of the radio and DVD player are integrated properly and working harmoniously without any conflicts or issues.
Remember, attempting these modifications may be complex and could potentially damage your vehicle's electrical system or affect the performance of the DVD player. It's highly advisable to have a qualified professional install the new radio for you.
