The biggest appeal of OTTOCAST Nano AI BOX: Two types of AI assistant functions
Original AI “Nano” | Specialized app operation assistant
Nano, a proprietary AI assistant developed exclusively for OTTOCAST Nano, specializes in intuitive app operation via voice commands .

OTTOCAST Nano AI BOX
How to start and examples of use
Activation word : “Hey Nano”
Main voice commands :
- “Guide me to XX” → Start route guidance on Google Maps
- “Play XX video on YouTube” → Launch YouTube and play video
- “Next song” “Previous song” → Music playback control
- “Volume up/down” → Volume adjustment
- “Make the screen brighter/dim” → Adjust screen brightness
Nano’s features and limitations
merit :
- Everything from launching the app to operating it is done entirely with voice.
- Compatible with major apps such as Google Maps, YouTube, and music apps
- Japanese voice recognition accuracy is good
Cons :
- Commands are strict : commands must be spoken exactly as they are in the standard format; they will not be recognized.
- Does not handle variations in language (e.g., “I want to go to XX” or “Take me to XX”)
- Limited number of compatible apps (expanded in future updates)
- No web searches or question-answering
ChatGPT-4 | Conversational Generative AI Assistant
The world’s most advanced generative AI, “ChatGPT-4,” is included as standard, allowing it to generate natural-sounding answers to a wide range of questions and casual conversations .
How to start and examples of use
Activation word : “Hey GPTT”
Usage scenarios :
- “What’s the weather like in XX prefecture this weekend?” → Search for weather information and answer
- “Tell me about the best tourist spots in XX” → Answer by summarizing tourist information
- “Say something funny” → Entertain your fellow passengers with jokes and small talk
- “Explain about ○○” → Knowledge search and learning support
Features and limitations of ChatGPT-4
merit :
- Handles complex questions and ambiguous expressions
- Understanding the context of conversation enables natural dialogue
- Drawing information from a broad knowledge base
- Educational use that answers children’s “why” questions
Cons :
- No app operation is possible : music playback and navigation settings are not possible
- Risk of hallucination (generating misinformation)
- Internet connection required (not available offline)
- GPT-4 information is only available up to April 2023 (limited up-to-date information)
Two AI strategies
| the purpose | Recommendation AI | reason |
|---|---|---|
| Navigation destination setting | Nano | Direct operation of Google Maps |
| Video and music playback | Nano | Consistent operation from app launch to playback |
| Tourist information search | ChatGPT-4 | Summarize web search results and provide answers |
| Chatting and killing time | ChatGPT-4 | Enjoy your drive with natural conversation |
| Child’s partner | ChatGPT-4 | Answer questions and play games |
Important note : The two AIs operate independently, which can interrupt the flow of conversation . For example, if you want to set navigation to a tourist spot after hearing about it through ChatGPT-4, you must end the conversation with ChatGPT-4 and then say “Hey, Nano” again to set the destination.
Advantages of OTTOCAST Nano AI BOX | 7 advantages discovered through actual use

OTTOCAST Nano AI BOX
1. “The driving experience of the future” realized through voice and AI
The biggest appeal is that you can safely operate it using only your voice while driving . With conventional CarPlay and Android Auto, you had to touch the screen to set a destination or play videos, but with the OTTOCAST Nano, you can do it all with just voice commands.
Practical example :
- While driving long distances on the highway, safely change your destination by saying, “Hey, Nano, take me to the next service area.”
- Get information while stuck in traffic by listening to “Hey, GP, what’s on the news today?”
- A child asks, “Why is the sky blue?” -> “Hey GP, explain to me in a way that a child can understand why the sky is blue” is an educational response
2. Expressive sub-display creates a “partner-like” feel
The facial expressions of the AI character displayed on the 1.83-inch OLED display bring a sense of life to this otherwise inorganic gadget.
Customizable display content :
- AI character facial expressions (multiple presets available)
- Analog/digital clocks (many luxurious designs)
- Music playback information (artist name and song title)
- Equalizer-style visualizer
Practical benefits :
- Even in vehicles where music information is not displayed on the original navigation system, it can be checked on the sub-display.
- Clock display adds a touch of luxury to your dashboard
- Visual feedback during speech recognition lets you see at a glance whether the AI is listening

Improved long-term reliability :
- Safe for long-distance driving in the summer
- Extending the life of the device
- Reduced risk of breakdown
7. Cloud SIM support for easy internet connection

| item | Cloud SIM | Smartphone tethering |
|---|---|---|
| Setup time | Auto-connect | Need to turn ON/OFF every time |
| Communication stability | 3 Carrier Automatic Switching | Depends on the smartphone signal |
| Smartphone battery | No impact | Large consumption |
| Data capacity | Additional purchases | Dependence on smartphone plan |
| Monthly fee | Only what you use | Depends on smartphone plan |

- Nano: No HDMI output → Rear seat monitor cannot be used
Affected users :
- Households using rear seat monitors in minivans, etc.
- When you want to show a different video in the back seat during a long trip
Alternative :
- Separate tablets and portable DVD players are available for the rear seats.
- Continued use of OTTOCAST P3
② Port reduction due to compact body size
- P3: USB Type-A x 2, Type-C x 1, HDMI x 1
- Nano: Type-C x 1 only
Why Nano is an “AI-specialized model” :
- Prioritizing compactness and cost reduction

- Isn’t it illegal to watch videos while driving?
-
According to the Road Traffic Act, drivers are prohibited from watching videos displayed on the display while driving. Any videos must be viewed by a passenger, and the driver must never watch the screen.
- How do I check compatible vehicle models?

- How much does the monthly communication fee cost?
-
It depends on how often you use it, but if you watch YouTube (standard definition) for about two hours on the weekend, you’ll use about 2-3GB per month. There’s no additional charge if you use smartphone tethering, and the cost for a cloud SIM starts from 699 yen per month.
- Which do you recommend, the Nano or the previous model P3?

Not suitable for :
- ❌ Those who require HDMI output to a rear seat monitor
- ❌ People on a budget (P3 and Tbox Ambient are better value for money)
- ❌ People who are not interested in AI voice control
- ❌ People who prioritize stability and completeness (AI functions are still in development)
final conclusion
The OTTOCAST Nano AI BOX is the perfect choice for those who want to “get ahead of the future of in-car entertainment .” It’s packed with features not found in conventional AI BOXes, such as voice interaction with ChatGPT-4, an expressive sub-display, and smooth operation thanks to the latest hardware.
On the other hand, there are some areas where it has “degraded” from the previous model , the P3, such as false positives in voice recognition, a feeling that the AI functions are still in their infancy, and the removal of HDMI output. If you are looking for “all-inclusive stability,” the P3 is the choice, while if you are looking for “the new experience of interacting with AI,” the Nano is the choice.
At around 60,000 yen, it’s not cheap, but it’s a worthwhile investment that will greatly improve the quality of your drive , helping to relieve boredom in passengers on long drives, keeping children from getting fussy, and preventing driver drowsiness . Best of all, you can continue to use it even if you change your car, so it’s not bad value for money in the long run.
“Dialogue with AI makes driving more fun and safer” — that’s the new car life proposed by OTTOCAST Nano AI BOX.
