Installation and Conversion Instructions Cayenne (9YA) 15/20 ENU 9163 9 PORSCHE Front Camera (Dashcam) Revision: This bulletin replaces bulletin Group 9 15/20, dated April 6, 2023. Model Year: As of 2019 Information: Retrofitting Figure 1 Note: The Porsche front camera (dashcam Figure 1) is affixed to the LEFT of the interior mirror (viewed in direction of travel) on the windshield and is connected to the vehicle electrical system. It is ideal for making video recordings of driving situations and while parking. It can be configured and operated using a related app on your smartphone. Recorded videos are stored on the supplied SD card and previous recordings are overwritten. If the dashcam detects a shake/vibration or if the radar sensor is triggered, the recorded video is stored separately and not overwritten. Recordings can be downloaded directly from the SD card or via the app. Tequipment Aug 11, 2023 Page 1 of 21 9 Cayenne (9YA) 9163 ENU 15/20 Installation and Conversion Instructions Information Important information for customers/customer service advisors: • Ask customers to download and install the "Porsche Dashcam App" from the App Store (Apple or Google Play) on their device (smartphone/tablet) in advance.
