Target Audience: Tesla owners in the United States
Key Takeaway: Grok has evolved from a basic chat assistant into a powerful natural-language navigation co-pilot. It works seamlessly with FSD (when enabled) for real-time route changes, but it's still in Beta, can't control vehicle hardware, and doesn't make FSD driving decisions.
1. Core Features Already Available (as of January 2026)
1. Advanced Natural-Language Navigation (Most Useful Feature)
Just speak a full command with multiple stops, time constraints, or preferences in one go.
Example Commands (say them directly):
- “Navigate to the office, stop by the post office on the way, and get there before 5 p.m.”
- “Find a 4-star-or-higher Italian restaurant nearby, add the closest Supercharger, and avoid traffic.”
How it works: Grok searches locations, plans the optimal multi-stop route, and displays it on the car's map. Set Grok's personality to “Assistant” and ensure software is 2025.44.25 or later.
2. Working Alongside FSD (Navigation Layer Only)
When FSD is active, Grok acts as a real-time navigation helper:
- Change destinations mid-trip, add stops, or tweak routes on the fly.
- Offers smart suggestions based on current location, battery level, time, etc.
Important note: Grok handles navigation only—it does not control FSD maneuvers (lane changes, braking, etc.) or explain driving decisions.
3. Advanced Conversation & Context Awareness
Supports back-and-forth chats, logical reasoning, and fun banter.
Switch personalities (Assistant / Storyteller / Unhinged, etc.).
Example: If battery is low, Grok might proactively say, “There's a Supercharger nearby—want to head there?”
4. Activation Methods (Current)
- Press and hold the right-side steering wheel voice button
- Or go to touchscreen → App Launcher → Grok
(“Hey Tesla” still wakes the standard voice system; “Hey Grok” wake word is in development and expected soon.)
2. Features & Limitations That Are Clearly Not Available
1. No Control Over Vehicle Hardware
Grok cannot adjust AC, seat heaters, windows, media playback, frunk/trunk, etc.
Use the traditional “Hey Tesla” voice commands or manual controls instead.
2. Does Not Participate in FSD Core Decision-Making
Grok is purely a navigation assistant and conversational partner—it cannot generate or alter FSD's driving strategy.
3. Requirements to Use It
- Hardware: AMD Ryzen processor required (most models built mid-2021 and later).
- Software: 2025.26 or newer (navigation needs 2025.44.25+).
- Connectivity: Premium Connectivity subscription or stable Wi-Fi (no offline mode).
- Region: Fully rolled out in the United States.
4. Still in Beta
Performance can be affected by background noise, network lag, or unclear commands. Drivers must always review and confirm routes.
3. Quick Reference: Feature Summary Table
| Feature Category | Available? | Details & Notes |
|---|---|---|
| Multi-stop natural-language navigation | ✅ | Most powerful everyday feature; supports time/preference constraints |
| FSD active + route adjustments | ✅ | Change routes mid-trip, but no control over FSD decisions |
| Context-aware conversation | ✅ | Real-time suggestions using location, battery, etc. |
| Hands-free wake word | ⏳ | Currently requires button press; “Hey Grok” coming soon |
| Control AC/windows/media | ❌ | Use traditional “Hey Tesla” voice commands |
| Intervene in FSD driving decisions | ❌ | Navigation assistant only |
| Offline use | ❌ | Requires internet connection |
| Deep personalized learning | ❌ | Currently limited to single-trip context only |
4. Frequently Asked Questions (FAQ)
Q1: Can my 2019 Model 3 use it?
A1: Only if the infotainment has been upgraded to AMD (very rare). Most 2019–2021 models still have Intel chips and do not support Grok.
Q2: Will Grok learn my driving habits?
A2: Not yet. Context awareness is based on the current trip only—no long-term learning.
Q3: Is there an extra cost?
A3: Software updates are free, but you need Premium Connectivity (about $9.99/month) for cellular data. Wi-Fi works for free.
Q4: How do I get the best experience?
- Set Grok personality to “Assistant” to unlock navigation commands
- Speak clearly and give complete commands at once
- With FSD on, just say “Change to X” or “Add a charging stop”
- Check for updates regularly (2026.2.x improves Cybertruck support)
Summary
As of January 2026, Grok is the most practical navigation AI co-pilot for U.S. Tesla owners—especially great for road trips or FSD users. It makes “talking to your car to plan routes” a reality, but always supervise it, and it doesn't replace traditional voice commands for controlling the vehicle.

Pro Tip to Get Started
Right now, check your vehicle's software version and processor type (Controls → Software → Additional Vehicle Information). If eligible, try saying: “Navigate to the airport, add a coffee stop along the way, and alert me if battery drops below 20%.” You'll notice the upgrade immediately!
