Tools You’ll Need
Before starting the installation, gather the following tools and materials:
- T-Style XL Radio Kit
- Pry tools (plastic trim removal tools)
- Socket wrench set
- Screwdrivers (Phillips and flathead)
- Electrical tape
- Wire connectors
- A USB-to-auxiliary cable (if necessary)
- Torque wrench
Step-by-Step Installation Process
Step 1: Disconnect the Battery
The first step in any vehicle electronic installation is to disconnect the vehicle’s battery. This ensures that you don’t accidentally short-circuit any electrical components while working on the radio. Use a wrench to remove the negative terminal from the battery and secure it to the side.
Step 2: Remove the Old Radio
Using a plastic trim removal tool, gently pry off the dashboard panel surrounding your stock radio. Take your time to avoid cracking the trim. Once the trim is removed, locate the screws that are securing the radio in place and use a screwdriver to remove them.
Next, pull the radio out of the dash and disconnect the wiring harnesses and antenna cable connected to the back of the unit. Keep track of any screws or clips, as you may need them later for the installation of the T-Style XL Radio.
Step 3: Prepare the Wiring Harness
The T-Style XL Radio will come with a custom wiring harness that needs to be connected to your Jeep’s electrical system. Carefully match the wires from the new radio to the corresponding wires from your vehicle using the provided wiring diagram.
In some cases, you may need an adapter to match certain connectors. If the radio includes additional features like a backup camera or external microphone, be sure to connect these as well.

Step 4: Connect the Wiring
Now it’s time to make the electrical connections. Connect the wiring harness from the T-Style XL Radio to the vehicle’s power supply and other necessary connections, including the antenna and auxiliary input. Use wire connectors or electrical tape to secure any loose connections and avoid potential short circuits.
Step 5: Install the T-Style XL Radio
Once the wiring is set up, it’s time to mount the T-Style XL Radio into the dash. Align the radio with the mounting holes and slide it into position. Secure the unit using the screws you removed from the stock radio. Make sure it fits snugly in place.
If you’re installing a backup camera or external microphone, carefully mount them in their respective locations, ensuring that all wires are neatly tucked away and free from interference with other components.
Step 6: Reassemble the Dashboard
With the radio securely in place and the wiring connected, carefully reassemble the dashboard. Start by placing the trim panel back around the radio, ensuring that it clips into place. Double-check that all screws are properly tightened.
Step 7: Power Up the System
Once everything is securely installed, reconnect the battery. Start the vehicle and power up the T-Style XL Radio to ensure that it’s functioning properly. You should see the Android interface on the screen, ready to guide you through setup.
If you have any specific settings you need to adjust, such as screen calibration, time zone, or audio preferences, now is the time to do so.
Step 8: Test All Features
Finally, test out all the features of your new T-Style XL Radio. Check the following:
- Bluetooth connectivity
- GPS and navigation
- Sound system and audio settings
- Backup camera (if installed)
- Apple CarPlay/Android Auto functionality
Make sure everything works smoothly and that there are no issues with the installation.
