Why can't I connect to the driving map? ——Cause analysis and solutions
Recently, many Driving Map users have reported abnormal device connections, resulting in the inability to use navigation, fuel consumption statistics and other functions normally. This article will combine hot topics and user feedback from the entire network in the past 10 days, structurally analyze the reasons for driving map connection failure, and provide solutions.
1. Statistics on high-frequency causes of driving map connection failures
| Ranking | Fault type | Proportion | Typical performance |
|---|---|---|---|
| 1 | Device power supply abnormality | 42% | Indicator light does not light up/flashes |
| 2 | APP version is too old | 28% | Prompt "Requires upgrade" |
| 3 | Poor contact of OBD interface | 18% | Data disconnection while driving |
| 4 | Vehicle system conflict | 9% | Black screen on startup |
| 5 | SIM card arrears | 3% | No network signal |
2. In-depth analysis of specific issues
1. Hardware connection problem
According to data from Chezhi.com in July, the OBD-II interface failure rate increased by 15% year-on-year. suggestion:
- Check whether there is any foreign matter in the interface
- Try changing the interface location (some models have spare interfaces)
- Use physical reset button (press and hold for 10 seconds)
2. Software compatibility issues
The recent Android 14 system update has caused a large number of connection failures. Jiatu officials have released the v5.3.1 emergency patch on July 20. Please note before updating:
- Back up trip data
- Turn off battery optimization
- Allow high power consumption in the background
3. Server-side exception
On July 25, due to server expansion, there was a 2-hour service interruption in East China. This can be confirmed by:
- Visit the official website status page
- Test other networking features
- Check the official Weibo announcement
3. Scenario solutions
| Usage scenarios | Check steps | emergency plan |
|---|---|---|
| New car connected for the first time | 1. Confirm model compatibility 2. Check fuse status 3. Complete initial calibration | Use mobile hotspots instead of in-car networks |
| Disconnected after upgrade | 1. Roll back to the previous version 2. Clear APP cache 3. Reset network settings | Export data via computer |
| Disconnected while driving | 1. Check voltage stability 2. Test OBD power supply 3. Eliminate electromagnetic interference | Navigate using offline maps |
4. Effective techniques tested by users
Organized according to hot posts on Zhihu (methods with >500 likes):
•Voltage stabilization method:Start the engine before plugging in the device
•Network reset method:Turn off the device and phone Bluetooth simultaneously for 30 seconds
•Position calibration method:Keep the device stationary in an open area for 3 minutes
•Interface protection method:Use electronic contact cleaner to treat interfaces
5. Latest updates from manufacturers
The driving technical team revealed in a live broadcast on July 28:
- Dual-mode connection technology (Bluetooth + 4G dual channel) will be launched in August
-Old equipment can enjoy trade-in subsidies
- Establish city-level quick repair service outlets (the first batch covers 15 cities)
If none of the above methods work, we recommend:
1. Dial 400-800-8800 for technical support
2. Provide equipment SN code and fault video
3. Make an appointment for offline testing service (requires proof of purchase)
