The display is the core interaction interface of LAMTTO RC series CarPlay screens. Screen clarity, touch responsiveness, brightness, and night mode directly affect your driving experience.
However, some users may encounter issues such as touchscreen lag or freezing, screen flickering, poor visibility in sunlight, night mode not working, and navigation lag.
The good news: Most screen issues are easy to fix.
1. Screen Lag / Slow Response / Freezing
Solutions:
- Close background apps on your phone
- Restart and reset the CarPlay device
- Remove SD card and rear camera (to rule out interference)
- Test with another phone
Note: Wireless CarPlay devices rely on your phone — some delay is normal.
2. Screen Flickering / Jumping
Solutions:
- Use the original car charger (important)
- Plug charger directly into cigarette lighter (no adapters)
- Reset the device
- If unresolved → hardware issue
3. Navigation Volume Too Low
Solutions:
- Test navigation volume without CarPlay
- Adjust volume while Siri is speaking
- Adjust music and navigation volume separately
- Check car audio settings
4. Night Mode vs Map Dark Mode
These are two separate systems: CarPlay night mode and map app dark mode. Map apps control their own theme. Android cannot sync time with CarPlay, so manual switching may be required.
5. Messages / WhatsApp Not Showing
Safety restrictions mean no text display while driving. CarPlay supports voice reading and voice replies instead.
6. Google Maps Night Mode Not Working (DVR models)
- Check map app settings
- Verify system time
- Enable night mode
- Reset device
7. How to Adjust Volume
- Steering wheel / dashboard controls
- CarPlay screen volume slider
- Phone volume buttons
Tip: Adjust during Siri → navigation volume; adjust during music → media volume.
8. Screen Too Dim / Cannot Adjust Brightness
Set brightness to maximum, disable auto brightness, reset device. If still dim → hardware issue.
Final Thoughts
Most LAMTTO RC display issues are caused by power instability, phone performance, system limitations, and environmental conditions.
Always use the original charger, avoid direct sunlight exposure for long periods, and keep your phone system updated.
