A CarPlay screen fitted with a rear-view camera can turn the trickiest daily manoeuvre, reversing into a tight or dark garage where the mirror does not reach the bumper, into a simple task. The image appears on screen with guide lines, and the same unit brings smartphone navigation to a car that left the factory with a basic two-button radio. Five models, all currently discounted, offer this in different ways, and the main difference between them is how much of the dashboard has to be touched to fit one.
How the wiring and recording work
All five screens do the same thing at the front: wireless CarPlay and Android Auto, with no cable running to the phone. What separates them is what happens behind the dashboard. The reversing camera cable runs from the number plate, along the boot sill and through the cabin to the screen, with power drawn from the positive wire of the reversing light. Put the car in reverse, the light gets power, the camera wakes up and the image appears automatically, with nothing to press.
Continuous driving footage is a separate feature, handled by a DVR: a second camera facing the road that records in a loop onto a microSD card, overwriting the oldest footage once the card fills up. It is useful for settling disputes after a knock in a roundabout. Some models in this group include a DVR as standard, some offer it as an optional variant, and some only cover what happens behind the car.
Sound is where most buyers are caught out. None of these screens plug into the car's speakers. Instead they send audio over FM radio to a free frequency, or over Bluetooth if the factory radio supports it. Navigation prompts come through clearly either way, though finding the right FM dial for music can take a little patience.
Hippcron XSP-2: a screen you can remove at a red light
The Hippcron XSP-2 attaches with a suction cup to the dashboard or windscreen and requires nothing to be removed from the car. It measures 7 inches, 178x98mm and weighs half a kilogram, so it can be fitted or taken out without tools, making it an option for an older car whose centre console stays untouched, or for a car about to change hands.
Resolution is 1024x600, enough for a map and for the rear camera image, which is available depending on the variant chosen. It responds to voice commands without needing to touch the screen. One buyer said it reacted well to voice commands and was a good size that did not block visibility, something that matters in a small car, where a badly placed screen can cover half a junction.

Jansite: rotates between horizontal and vertical
The Jansite CarPlay screen steps up the sharpness, with a resolution of 1920x1080, the sharpest in the group, across 7, 8 or 9-inch versions depending on variant. It mounts using a combination of a magnetic support and a suction cup, so the screen detaches with a tug and clicks back into place without needing to line it up, useful for a car parked on the street.
Its distinguishing feature is that it can be set to horizontal or vertical orientation, mirror-style. In vertical mode the map reads more like it does on a phone, showing more road ahead and fewer side streets, and the whole unit weighs 850 grams, enough to keep the mount steady. One user said the suction mount was so strong that it did not fall off even in their car, which shakes a great deal. In vertical mode, Android Auto text appears somewhat small; in horizontal mode the text returns to its usual size.

Srnubi portable: fits a standard radio slot
This model takes a different approach. The Srnubi CarPlay unit comes in a 1 DIN format, the standard radio-slot size, so it can sit in the dashboard without suction cups or adhesive if the car still has that slot free. It is available in 7 and 10-inch versions, with the screen mounted onto the body of the unit.
It has no DVD or CD player, and that absence is what allows the compact format. In exchange, it has a TF card slot and can take an optional rear-view camera, so the original radio slot ends up holding something useful for navigation today rather than a disc player nobody has used in a decade. It suits anyone who wants a factory-fitted look without cutting into the dashboard.

Srnubi 10.26-inch: a screen that stays fixed in place
From this point on, these are not screens removed at a traffic light. This 10.26-inch panel is installed onto the dashboard, positioned so the driver barely has to look down, and it stays there. The larger surface shows most with the camera in use, since the rear image fills the whole screen instead of a small box, and the guide lines can be read without leaning forward.
Variants are available with and without 4K recording, with different cameras included in the package, so a buyer can start with the basic version and keep only the reversing function. It adds an AUX input for audio over cable, if the car's radio still has one. One owner who already drives with it said the screen brightness let them see the map very clearly, and that the camera had very good resolution, a detail that matters when the sun is low in August.

11.26-inch CarPlay screen: cameras front and rear
This is the largest screen in the group, and it records both ahead of and behind the car at the same time. It measures 11.26 inches with a resolution of 1920x720, a panoramic format that puts the map on the left and music on the right without either getting in the way, running on a V553 processor with 1GB of RAM.
Its dual-camera system is what earns it the top spot in this line-up: one lens faces the road and records in 4K onto a microSD card while driving, the other covers the reversing manoeuvre. In city driving, with roundabouts and parallel parking every day, that double image is worth more than any extra inch of screen. Pairing the phone for the first time requires reading the instructions carefully, but the connection then stays set.

Measurements to check before buying
Screen diagonal is the first thing buyers compare and the last thing that should decide the purchase. What actually needs measuring is the vertical gap between the top edge of the dashboard and the driver's line of sight: an 11.26-inch screen mounted too high eats into the windscreen on the right, while a 7-inch screen placed correctly bothers no one. With a suction mount on the glass, the rule of thumb is to avoid the area swept by the driver's wiper and the passenger airbag zone.
Weight matters more than it seems. Half a kilogram hanging from the glass is one thing, 850 grams is another, especially on a car with firm suspension driving over cobbles: the heavier the unit, the more leverage it exerts on the mount, which is where image shake comes from. A magnetic mount or a stand resting on the dashboard itself distributes that load better than a suction cup alone, high on the glass.
For the 1 DIN format, the measurement that matters is the slot, not the screen. If the original radio was ever replaced and the surrounding frame was trimmed, it is worth checking the housing before checking the diagonal.
What makes a dashboard screen last longer
A car parked in the sun in August turns into an oven inside, and that heat is the real enemy of these units, more so than mileage. Portable screens have a clear advantage here: they detach from the mount in seconds and can go into the glovebox or come home, which is also the best way to stop anyone breaking a window to steal one.
The suction cup's adhesive disc lasts well if the surface it sticks to is clean. A dashboard treated with silicone polish will not hold anything, so wiping the spot with isopropyl alcohol before fitting avoids most problems, and once the suction starts to lose grip, washing it with warm water and soap and letting it air dry usually restores it.
The memory card in models with recording is the part that wears out fastest, since it writes in a constant loop. It is worth using a microSD card designed for continuous video and formatting it from the unit's own menu every few months, a minute of work that avoids finding out on a bad day that the file was corrupted.
Common questions
Does it record all the time or only when reversing? It depends on the model. The rear camera activates with the reversing light and shows the image only during the manoeuvre; the front DVR, on models that include one, records from the moment the engine starts and keeps overwriting the oldest footage.
Does the car radio need to be replaced? Not with any of the five. The original radio stays in place and works as an amplifier when audio comes through FM or Bluetooth; only the 1 DIN model takes over the radio slot, because it is designed to.
Where does the phone go? In a pocket or on a charging pad, since the connection on all five is wireless, with no data cable to plug in each time someone gets in the car.
Choosing between them comes down to how much of the dashboard a driver is willing to touch: a suction-cup screen that comes off at a red light, or a fixed panel left in place for good. Once the camera is installed, drivers still tend to glance over their shoulder out of habit, a reflex that usually disappears by the third reversing manoeuvre.
