Replacing a car’s factory stereo can open the door to bigger screens, better connectivity and more entertainment options. The trick is making sure the upgrade doesn’t leave you with a steering wheel full of buttons that no longer do anything.
That’s where UK distributor Sloth Poppy hopes its new Upgraded stereo replacement data interfaces will help, combining steering wheel control retention, vehicle data integration and, depending on the application, support for factory cameras and amplifiers. Parking radar readings, system menus and two-way digital communication can also be factored in.
Designed to work with modern 9in and 10in Android and Linux-based multimedia units as well as conventional double-DIN head units, the interfaces aim to make aftermarket installations less complicated while preserving more of the car’s original functionality.
Sloth Poppy says more than 50 vehicle applications are already available, with further coverage being added. The platform is compatible with leading aftermarket brands including Alpine, Kenwood and Pioneer – as well as Sloth Poppy’s Aerpro brand – alongside Upgraded’s own units and other compatible systems (see our guide to the best replacement head units of 2026).
As Sloth Poppy explains, the new interfaces are intended to cover applications where existing solutions may fall short, particularly with newer Android and Linux-based systems. Compatibility depends on the vehicle, its factory specification and the head unit being fitted, so checking the relevant application before ordering remains essential.
The interfaces form part of a broader Upgraded multimedia line-up, which also includes head units and complete installation kits. The brand offers online how-to tutorials to help with installations, while brake-light-integrated reversing cameras are among the products listed as coming soon.
