Frequently Asked Questions

What SD Card Do I Need for Nextbase iQ 4K?
The Nextbase iQ 4K takes a microSD UHS-I (U3) card rated U3 or faster. 256GB or 512GB covers most owners, and the maximum is 512GB. Buy SanDisk, Lexar, Samsung or Kingston from a reputable seller: counterfeit cards are the most common cause of lost files.
What SD card does Nextbase recommend for the iQ 4K?
A U3 dash cam card: Nextbase's own cards or the SanDisk High Endurance.
What capacity should I get for the Nextbase iQ 4K?
256GB for most drivers, 512GB for long parking recordings.
Do I need to maintain the card in the Nextbase iQ?
Yes, reformat it every few weeks in the camera. Nextbase recommends it to keep write performance steady.
Is U3 required for Nextbase iQ 4K?
Yes. U3 guarantees 30 MB/s of sustained write, which keeps the Nextbase iQ 4K free of dropped frames, clips that stop early, or corrupted files. Faster cards work too.
What size SD card should I get for Nextbase iQ 4K?
256GB covers light use; 512GB suits heavy use. The maximum is 512GB.
Can I use older or slower cards with Nextbase iQ 4K?
Not below U3. Slower cards cause dropped frames, clips that stop early, or corrupted files. Check the card label for the U3 mark.
Is a UHS-II card faster in Nextbase iQ 4K?
No. The Nextbase iQ 4K has a UHS-I slot, so a UHS-II card runs at UHS-I speed. It only offloads faster in a UHS-II card reader.
Does the brand matter for Nextbase iQ 4K?
Yes. SanDisk, Lexar, Samsung and Kingston cards meet their rated speeds. Buy from the brand's store or a major retailer: counterfeit cards sold under those names are common on marketplaces.
What happens if I use the wrong card with Nextbase iQ 4K?
A card slower than U3 causes dropped frames, clips that stop early, or corrupted files. A card over the maximum capacity or in the wrong format may not be recognized.
How long will an SD card last in Nextbase iQ 4K?
It depends on write volume. Constant loop recording wears cards out, which is why high-endurance cards are rated in recording hours. Replace the card at the first error message.
