Lots of bugs to work out. CarPlay interface is a little boring and small despite plenty of screen. Some CarPlay readings only display in Celsius although Empirical selected in settings. Only used a few times but I’m excited for it to improve. Successfully connecting with vLinker MC **Developer response:** Thanks for the feedback. Due to CarPlay’s current design limitations, I’m not yet able to offer the fully custom and creative interface I have in mind, but I’m actively working on improving it and making better use of the available space. I’ll also look into the bugs you mentioned, including the Imperial/Celsius issue, as soon as possible. Thanks again for helping improve OpenOBD. ## Frequently asked questions about OpenOBD ### What is OpenOBD? OpenOBD turns your iPhone or iPad into a real-time car dashboard.
