Get a 128GB SanDisk High Endurance or MAX Endurance microSD card. Nextbase 222XR & 322GW Rear Camera Bundle uses a microSD Card rated U3 / V30. Avoid standard non-endurance cards—dashcams overwrite video non-stop and will quickly burn out standard consumer cards, causing frozen screens or 'SD Card Error'.
The official maximum supported capacity for Nextbase 222XR & 322GW Rear Camera Bundle is 128GB (tested up to 128GB). For the best balance of price and reliability, our recommended sweet-spot size is 128GB.
Dual-channel recording (front + rear camera simultaneously): 64GB ≈ 4 hrs • 128GB ≈ 8 hrs continuous loop.. Choosing 128GB gives plenty of headroom without overpaying.
Standard non-endurance cards are not built for continuous loop recording and their warranty is voided in dashcams. Standard consumer cards (such as SanDisk Ultra) are not built for continuous loop recording and wear out quickly. Crucially, Western Digital's official warranty terms explicitly exclude dashcam and surveillance use on standard consumer cards (only dedicated High Endurance and MAX Endurance models are covered by warranty). Requires constant sustained U3 / V30 write speeds, especially if a Rear Camera module is connected.
Setup requirement: exFAT (Format inside Dash Cam menu every 3–4 weeks). For best results, format a brand-new card directly inside the Nextbase 222XR & 322GW Rear Camera Bundle settings menu upon first installation to establish the correct cluster size for continuous loop recording. We recommend reformatting every 3–4 weeks to clear protected event files.
Yes. Unbranded or counterfeit marketplace cards frequently spoof their capacity or fail to sustain U3 / V30 write speeds, leading to corrupted recordings or 'Card Error' warnings. Stick to genuine, branded cards from a reputable retailer to ensure full manufacturer warranty coverage.
