“Debug data” is technical information about the modules in your car and their current and/or supported settings. Here’s how to send us such data: on iOS, open the slide-out menu from the left of the main screen in Carista, and pick "Debug menu" -> “Collect debug data”. On Android, open the slide-out menu and tap on the version label at the bottom of it five times in a row; pick “Collect debug data” from the new menu that shows up. On both platforms, the process of collecting debug data can take up to 40mins. When it’s done, you’ll be prompted to send it in a report; please follow the on-screen instructions to send it. If you’re using a WiFi adapter, you may have to disconnect from the adapter before you send it, in order to have Internet connectivity. Thanks for helping out by sending us debug data!
