Tesla's Grok integration is quietly becoming one of the most practical in-car AI assistants on the road. Two new capabilities are emerging: natural-language navigation that handles full errands end-to-end, and an upcoming ability to send text messages directly from the vehicle. Here's what we know, what works today, and what's still rolling out.
What can Grok actually do for navigation right now?
Quite a lot, based on real-world use. Whole Mars Catalog shared a firsthand account on September 14: he asked Grok to take him to an ATM, it navigated there and parked in front of the machine, then he said "take me home" and it drove him back and parked in the driveway — all via natural voice commands with no screen interaction.
According to background research, Grok supports multi-stop route planning with natural constraints — for example, "Navigate to the office, stop by the post office on the way, and get there before 5 p.m." It can also provide location-based reminders. When FSD is active, Grok assists with real-time navigation adjustments, though it does not yet directly control FSD maneuvers. Elon Musk has confirmed that a future software update will enable that deeper integration.
When is text messaging coming, and how will it work?
Whole Mars Catalog reported on September 14 that you will "soon" be able to use Grok in Tesla vehicles to send text messages from your phone.
According to Tesla's updated owner documentation, the feature will work through Grok's "Assistant mode" — you'd say something like "Text Mom saying on my way" and Grok handles the rest. Grok can already place phone calls today; text messaging is the next logical step. Tesla has not announced an official release date, but the feature is expected to arrive via an OTA update without requiring any hardware changes on most current vehicles.
Which vehicles support Grok, and what do you need?
Grok requires an AMD infotainment processor (MCU3) and software version 2025.26 or later. Vehicles with the older Intel Atom (MCU2) chip do not support Grok voice control. You also need either an active Premium Connectivity subscription or a stable Wi-Fi connection. Grok is currently in Beta.
How do you activate it?
Hold the steering wheel voice button, or say "Hey Grok" if you've enabled voice activation in your vehicle's settings. Once active, you can speak naturally — no need to memorize specific command syntax. Grok is designed to parse conversational requests, so phrasing like "find me a coffee shop near the highway on the way to work" works just as well as a precise address.
What other commands does Grok handle beyond navigation?
As of the 2026 Summer Update (software version 2026.26), Grok's command set expanded significantly. Drivers can use natural speech to place phone calls, search and play music, adjust climate settings, open the glovebox, and search through the Controls menu. Grok can also handle multiple commands within a single request — useful for chaining tasks without re-activating the assistant between each one.
Is Grok available outside the US?
Yes. Grok launched in eligible US vehicles in July 2025 with software version 2025.26, expanded to Europe in February 2026 (update 2026.20), and has since rolled out to additional international markets including Chile, Malaysia, the Philippines, Hong Kong, India, and Singapore as part of the 2026 Summer Update.
Text messaging is the feature most likely to change daily driving habits — keeping your eyes on the road while staying reachable is a genuine safety and convenience win. With navigation already handling full errand loops hands-free, the gap between what Grok can do and what a human co-pilot would do is closing faster than most owners have noticed. The next milestone to watch is FSD control, which Musk has confirmed is coming but hasn't been dated. For the latest on all software updates, keep an eye on the BASENOR feed.
