Description
9" Wireless CarPlay for the Mercedes C-Class W203 and CLC Non-Amplified, SWC Retained, Sub Frame Modification Required
Product Overview
The Aerpro AMDMC4 is a complete head unit upgrade kit for the Mercedes-Benz C-Class W203 (2004–2006) and CLC CL203 (2008–2011) in non-amplified specification. It replaces the factory head unit with a 9" capacitive touchscreen at 1024x600 resolution, bringing wireless Apple CarPlay and Android Auto, built-in DAB+ digital radio, and Bluetooth V5 to vehicles originally fitted with an older factory unit.
Steering wheel controls are retained via the included SWC interface harness and patch lead. Factory reverse camera, USB input, AUX input, and vehicle menu are not applicable or retained on this kit the head unit's own connectivity handles those functions. The kit includes the AM905D multimedia receiver, matte black facia kit, SWC harness, SWC patch lead, antenna adaptor, and a 720P AHD universal rear camera.

Frequently Asked Questions
What does "modification to the plastic factory sub frame" mean?
The factory dashboard in the C-Class W203 and CLC CL203 includes a plastic sub frame or bracket behind the head unit opening that must be physically trimmed or cut to create the clearance needed for the new head unit to seat correctly. This is a physical modification to the factory dash structure and is not reversible. Professional installation by someone familiar with W203 dash work is strongly recommended.
What factory features are retained after installation?
Only steering wheel controls are retained. Factory reverse camera, USB input, AUX input, and vehicle menu access are all not applicable on this kit. The head unit's own dual USB ports, wireless CarPlay/Android Auto, and Bluetooth replace the factory connectivity options.
How does the AMDMC4 differ from the AMDMC2?
The AMDMC2 covers a broader range including the Mercedes A-Class, B-Class, Sprinter, Viano, Vito, and VW Crafter, retains both SWC and vehicle menu, and includes multiple antenna adaptors. The AMDMC4 is specific to the C-Class W203 and CLC CL203, retains SWC only, uses a matte black facia, and uniquely requires a sub frame modification that the AMDMC2 does not.
Does this suit the W204 C-Class (2007-2014)?
No — the AMDMC4 is designed for the earlier W203 (2004–2006) and CL203 CLC (2008–2011). The W204 C-Class is a different platform and requires a different kit.
Is this a DIY-friendly installation?
Due to the required sub frame modification, this installation is more involved than a standard plug-and-play kit. It is recommended for experienced installers or automotive workshop fitting. Inexperienced installation risks damage to the factory dash structure.
