Updated October 2025

Powered by Merge Screens - OEM Retrofit Experts in Wireless Apple CarPlay & Android Auto Integration

Why CarPlay Is Essential in 2025

Apple CarPlay has become the benchmark for in-car connectivity. It brings navigation, hands-free communication, and music streaming into one seamless interface, helping drivers stay focused while on the road. For today’s vehicles, CarPlay is more than a convenience — it’s an upgrade that enhances safety, comfort, and even resale value.

At Merge Screens, we design retrofit solutions that bring CarPlay to vehicles that didn’t originally include it. Our plug-and-play modules maintain your factory display, steering wheel buttons, and backup camera — offering full Apple CarPlay and Android Auto integration without changing your vehicle’s look or controls. Compatible brands include BMW, Lexus, Audi, Mercedes, Toyota, and more.

1. Head Unit vs. CarPlay Module — What’s the Difference?

Aftermarket Head Units

An aftermarket head unit replaces your factory stereo entirely with a new touchscreen interface. This option is ideal for older vehicles or those without any built-in screen.

Pro

● Large 9–12-inch displays

● Modern operating systems and audio processing (DSP)

● Customizable interface and layout

Con

● Replaces your original dashboard design

● Often requires professional installation

● May affect integration with steering buttons or cameras

CarPlay Retrofit Modules (Merge Screens Specialty)

CarPlay modules are the preferred choice for drivers who want advanced features without losing their factory interface. Merge Screens modules add Apple CarPlay and Android Auto while preserving your car’s OEM design and controls.

Key Benefits

● Works with your existing screen

● Retains steering wheel buttons, reverse camera, and OEM dials

● Plug-and-play setup — no coding or dashboard modification

● Supports both wired and wireless CarPlay

Best For: BMW, Lexus, Audi, Mercedes, Toyota, Mazda, and other 2012–2023 vehicles equipped with factory displays.

2. How to Choose the Right CarPlay Gear (Buyer Checklist)

Choosing the right CarPlay system depends on your car’s setup, preferences, and goals. Here’s what to check before buying.

a) Compatibility

Each Merge Screens module is purpose-built for specific makes and systems to ensure seamless integration.

Example

● BMW CarPlay Module — Compatible with iDrive NBT/CIC systems (2012–2020). Supports the factory microphone, iDrive controller, and full system interface.

b) Wireless vs. Wired CarPlay

Feature	Wireless	Wired
Convenience	Connects automatically when the car starts	Requires manual plug-in
Battery	May consume phone battery	Charges while connected
Connection Stability	Can drop under weak signal	Maintains consistent link

 

Merge Screens modules include both options, giving you flexibility depending on your needs.

c) Screen Quality

Unlike full head unit replacements, Merge Screens modules keep your original display intact. This ensures:

● Native screen resolution and aspect ratio

● No image distortion or stretched interface

● Full use of touch or joystick controls

Pro Tip

Older models with resistive touchscreens (such as early Lexus or Audi vehicles) can still control CarPlay through the OEM dial or joystick — no touchscreen required.

d) Sound System Integration

Merge Screens modules work seamlessly with premium factory audio systems, maintaining the clarity and depth of the original sound setup. Compatible brands include:

● BMW Harman/Kardon

● Lexus Mark Levinson

● Audi Bang & Olufsen

● Mercedes Burmester

The integration preserves amplifier settings and equalization, so your music sounds exactly as intended.

e) Firmware Updates and Support

Each Merge Screens module comes with lifetime support and firmware update access to keep compatibility with future iOS or Android releases.
 Customers receive:

● Step-by-step PDF guides and video tutorials

● Email and chat support during installation

● Update notifications for performance enhancements
