If you’ve ever wished to glance at your glucose readings right from your car’s dashboard, this might be your favorite diabetes tech hack yet. With the right setup, real-time CGM data—like Dexcom or Lubre readings—can now appear directly on Apple CarPlay, making it easier to keep track of glucose levels while driving, hands-free.
This setup works by connecting Dexcom data (or other CGMs integrated via Nightscout) through SugarMate, a companion app that syncs glucose readings into Apple’s ecosystem. Once SugarMate is connected, it automatically feeds your CGM data into Apple iCal, allowing readings to show up across multiple Apple devices—including the iPhone Lock Screen, Mac calendar widget, Apple Watch face, and now, even your CarPlay dashboard.
For those who love automation, this feature doesn’t stop there. You can even ask Siri for your current blood sugar by setting up a simple Siri Shortcut. Once configured, all you have to say is, “Hey Siri, what’s my blood sugar?” and she’ll pull the latest Dexcom reading instantly.
The setup process includes:
Installing SugarMate and linking it with your Dexcom account.
Syncing SugarMate to iCal so glucose values appear as calendar entries.
Enabling CarPlay integration to display readings right on your car’s screen.
Setting up Siri voice control for quick glucose checks without opening an app.
For people who spend a lot of time driving, this integration can be a total game-changer—keeping glucose visibility within reach, without adding distractions or complexity.
