When upgrading or replacing the head unit in your Porsche, it’s crucial to know which version you're dealing with to ensure compatibility and functionality. Porsche's OEM head units, known as the Porsche Communication Management (PCM) systems, have evolved over the years, with each version offering distinct features and design elements. This guide will help you differentiate between the various PCM models.
1. PCM 3.0 - CDR Head Unit
The PCM 3.0 system is an older version, typically found in Porsche vehicles from around the mid-2000s to early 2010s. Here are its key features:
-
Screen Design: The screen is relatively small and has a less sleek design compared to newer models.
-
Functionality: Includes basic audio functions, navigation, and a simple interface with the option to connect an external CD/AUX input.
-
Physical Buttons: The control buttons below the screen are quite tactile and are not integrated into a touchscreen system.
How to Identify:
Look for the "CDR" logo on the display or control buttons. The screen also tends to be more recessed within the dashboard. This is a sign of an older, less integrated system.
