I read owner reviews and forum posts about both mirrors. Their experiences shaped this guide. If you buy through a link here, I may earn a commission at no extra cost to you.
If you want a replacement rear view mirror dash cam, start with the view from your driver’s seat. Pick the AUTO-VOX V5 Pro if its built-in front lens has a clear view of the road. Pick the T9 Pro if you need to place that lens away from the mirror. Both replace your stock mirror and record front and rear views. Both need a wire to the rear camera.
Replacement rear view mirror dash cam comparison at a glance
| What you get | AUTO-VOX V5 Pro | AUTO-VOX T9 Pro |
|---|---|---|
| Front lens | Built into the mirror | Detaches for separate placement |
| Mirror mount | Replaces your stock mirror | Replaces your stock mirror |
| Screen | 9.35-inch touch screen | 9.35-inch touch screen |
| What it saves | Front and rear clips | Front and rear clips |
| Rear camera wire | Check kit length for your car | 20-foot cable listed |
Both offer loop recording [new clips replace old ones]. The live rear view and the saved clip serve different needs. You can use the screen to see past a loaded back seat, then play a saved clip after your trip.
Where will the front camera sit?
V5 Pro: Keep the lens and mirror together
The V5 Pro makes sense if you want one unit at the top of the glass. You can skip the search for a second front camera spot. The trade-off is that the mirror mount sets the lens location.
Look at the glass just ahead of your mirror. Does a large plastic cover sit beside the mount? Compare its edge with the lens position in the product photos. Even a small overlap is worth checking before you order.
T9 Pro: Place the lens where the glass is clear
The T9 Pro gives you more choice if that cover gets in the way. You can set the mirror where you like it and place the front camera off to one side. Allow room for its lead when you pick a spot.
Before you mount the lens, check where to place a dash cam near windshield sensors.
That extra choice has little value if your mirror already has a clear view. Also check the model name in your cart. The T9 Pro includes a front camera. The standard T9 lists its front camera as a separate purchase.
What owners found after fitting each mirror
V5 Pro in a Ford Maverick
A Maverick Lariat owner replaced the stock mirror and saved both views to a memory card. The part worth noting was the power hookup. The owner used two types of fuse tap [a plug for a fuse slot] in the same truck. Ask what your car needs before you price the job.
If fuse taps are new to you, our dash cam hardwiring guide explains the power connections.
Several V5 Pro owners also described a blank screen after a software update. One could still hear the startup sound and returned the unit after working with support. Those posts don’t tell us how often this happens. If you need an update, give support your current version before you load a file.
T9 Pro in a Hyundai Ioniq 5
An Ioniq 5 owner fitted a T9 Pro and used it to record both ends of the car. In rain, the rear image looked a little hazy. The owner still found it easier to see through that feed than through the wet back glass.
That detail matters if rain is why you want a digital mirror. Check where spray lands on the back of your car after a wet drive. Can you reach the lens to wipe it once you park?
What to check before you remove your stock mirror
- Match the mount. Send AUTO-VOX a photo of the mirror base, plus your car’s year, make, model, and trim. Ask which bracket fits. One 2025 Civic Sport owner struggled to find a match for the T9 Pro.
- Check the features you use. Look for garage door buttons, an auto-dim switch, or other controls on your mirror. Ask which ones you can keep after the swap.
- Measure the cable path. Trace the planned route all the way to the rear lens. On a hatch, include the path around the opening. Compare that length with the kit you plan to buy.
- Check both clips. Before you tuck the wires away, park and make a short recording. Play both files. Look for a blocked corner up front or too much bumper in the rear view.
Can either dash cam strap over your existing mirror?
Both Pro models use a replacement bracket. If you want to leave your stock mirror in place, look for a kit that shows straps around the original glass. To keep your mirror, check how the WOLFBOX G840S straps on. A photo of the screen alone won’t tell you how it mounts.
Which mirror fits your car?
Before you choose a replacement rear view mirror dash cam, settle two questions. Which bracket fits your car? Where can the front lens see clear glass? If both models fit, the V5 Pro keeps the front setup in one piece. The T9 Pro earns its place when moving the lens solves a problem you can see from your seat.
You can compare the mirror kits at AUTO-VOX. Check the bracket and cable in your chosen kit before you order.
