How To Install a Car Stereo Head Unit
Your old car needs Apple CarPlay.
Time Needed: 1-3 Hours, Difficulty: Beginner-Moderate, Cost: $80-Thousands
What kind of person are you? Are you the type who will live with a worse quality of life in order to maintain an aesthetic? Or are you the type who upgrades life no matter how it looks?
We’re talking about car interiors and the stereo head units that demand all the attention front and center. For years, I refused to update my 2003 Acura RSX radio because I liked the way it looked and appreciated keeping it stock for the time period. I replayed CD after CD until the system literally quit on me.
After years of denying the inevitable, I switched to a Pioneer DEH-S6010BS head unit with a built-in USB port, aux port, and hands-free Bluetooth capability to stream Spotify. Best of all, it was a super-cheap single-DIN unit that still had a CD player for all of my old tuneskis.
Removing part of a dashboard and messing with wires can seem intimidating, but I promise you, with some instruction and careful wrenching, it’s a pretty simple job. Grab your new stereo, don’t forget the adapters, and let’s get to work.
The Safety Brief
Installing a new stereo head unit is not too inherently dangerous, but you’re still dealing with tools, electricity, and sharp metal. In the spirit of being overly precautious, it’s best to do the work with a pair of mechanic gloves and some safety glasses.

The Job: How To Install a Car Stereo Head Unit
Every car stereo installation will be slightly different due to that particular vehicle’s design, but in general, these are the steps you will need to take to get to your stereo, remove the stereo, and replace the stereo.
- Read the instructions in your service manual on how to remove your specific stereo.
- WIth your car in park and cooled down, pop the hood and detach the negative terminal.
- Use the panel removal tools to pop off any dashboard pieces, panels, or components to get to the stereo.
- Unplug any connectors that are attached to the panels. Use tape and a Sharpie to label the wires if you need to.
- Remove the screws/bolts holding the stereo into the dashboard. You’ll likely find at least four of them.
- Slowly and carefully pull the head unit out. You might need an included small metal tool that will release the head unit from brackets or a metal case. They look like small pins or keys.
- Disconnect the antenna wire on the back side of the head unit.
- Disconnect the wiring harness on the back of the head unit.
- Remove the old head unit completely.
- Next, you will need to install the wiring harness that comes with your new stereo head unit. Read the instructions for what each wire does and label them with tape and a Sharpie if that helps.
- Connect the wires on the wiring harness to the car’s wiring by matching up the colors and linking them together with Posi-Taps.
- Depending on the car, you might need to also connect things such as the reverse wires, parking brake wires, steering wheel control wires, microphone wires, or any other feature specific to your ride.
- Assemble the dashboard radio adapter kit, if necessary.
- Install the kit onto the radio or into the dashboard, if necessary.
- Route the hands-free microphone and its wire through the dashboard and up the A-pillar trim and headliner, if you have the option, then plug it into the stereo.
- Reconnect the antenna cable, the wiring harness, and any other wires.
- Tuck the wiring into the cavity out of the way.
- Slide the head unit back into the cavity and attach the screws.
- Put any dashboard panels in their correct positions and attach accompanying wires or connectors.
- Before you reattach the panels, reattach the battery cable and turn the car on to test the radio out.
- If everything works, put it all back together, and attach the included faceplate trim.
Well done, you now have a modern radio!
