NAV-TV develops vehicle-integration products that help connect aftermarket equipment to factory audio systems and displays. Its range covers digital audio interfaces, camera integration, selected smartphone interfaces and radio-replacement solutions. The common objective is to add useful capability while working with the vehicle’s existing electronics and controls.
For 12 Volt Outlet customers planning an upgrade, the most important question is which factory system the vehicle actually has. A familiar model name or a matching screen size is only a starting point. This guide explains NAV-TV’s role, representative products and the compatibility details that should shape an installation.
A brand focused on factory-system integration
NAV-TV describes itself as an American manufacturer and distributor of automotive safety, entertainment and convenience products. Its published company information emphasizes improving existing radios and color monitors. That focus helps explain the breadth of its catalog: some products add a camera, some make aftermarket amplifiers possible, and others support a change of radio while retaining selected factory equipment.
The manufacturer’s documentation shows an established progression across these categories. Its BMW56-N camera-interface manual is dated 2016, a ZEN-M audio-interface manual is dated 2018, and ZEN-25 documentation followed in 2020. Those dated documents provide a concrete view of the brand’s work without relying on an unverified founding story. Today’s catalog also includes newer Ford A²B interfaces and Harley-Davidson integration products.
Choose the integration job first
Start by deciding what stays in the vehicle and what changes. Adding amplifiers while keeping the factory radio calls for a different signal path from installing a new radio while keeping the original amplifier. A camera interface has another job: bringing a compatible video source onto the existing display. Selecting the right category first narrows the search considerably.
A product name can sound broadly applicable while its actual compatibility is tightly defined. The radio generation, original amplifier, vehicle market, connector type and installed options can all matter. Look for the precise kit number and its instructions rather than treating every product in a family as equivalent.
ZEN audio interfaces and the factory signal
NAV-TV’s ZEN range provides ways to use signals from supported factory audio networks in an aftermarket system. Depending on the product, the interface supplies analog RCA outputs, a TOSLINK digital output or both. The range includes interfaces for different networks, including MOST, A²B and GM AVB applications. These network names identify different integration requirements, not a universal connection standard.
For an amplifier upgrade, the interface is the starting point for the signal path. The installer still needs to decide how the outputs will reach amplifiers or a compatible processor, which speakers each channel will drive, and how the system will be tuned. A successful installation also preserves the supported everyday functions, such as volume control and phone audio, in the way the specific kit describes.
ZEN-25 for supported BMW MOST systems
The ZEN-25, kit NTV-KIT969, is documented for supported BMW factory-amplified MOST 25 systems. It provides twelve analog RCA outputs and a stereo TOSLINK output. NAV-TV describes retention of functions including volume, balance, tone controls and telephone audio, with factory fader operation specified for the analog outputs.
The product also offers configurable routing for music, phone audio and warning sounds. Its documentation describes two time-alignment settings selectable through the factory Logic 7 control. These features matter when planning which speakers will reproduce calls and alerts. The compatibility check still needs to establish the actual factory fiber-optic amplifier and radio configuration, rather than assuming every BMW of a given age uses the same system.
ZEN-M and the importance of the connection type
The ZEN-M, NTV-KIT871, is an example of why a network label needs further detail. NAV-TV documents it for supported MOST-150 applications, with twelve analog RCA outputs and TOSLINK. Its instructions address selected Mercedes NTG5-family systems and identify retained controls and phone functionality, including an analog-only qualification for full fader operation.
Two restrictions deserve attention before purchase. The manufacturer excludes vehicles using MOST150 over a coaxial connection. It also states that systems without the original amplifier or fiber connection require the separate ZEN-M-PRG programming solution before installation, while factory-amplified vehicles do not require that step. The physical connection and original equipment therefore belong in the compatibility check from the outset.
Ford and GM A²B integration
The ZEN-A2B PLUS, NTV-KIT1033, is described as an amplifier-replacement interface for supported Ford and GM A²B applications. The manufacturer lists six analog RCA channels and TOSLINK output, with a configuration switch for the supported vehicle family. Its published description also discusses control of certain factory head-unit amplifier channels in compatible Ford B&O systems.
That last detail is important because a factory system can distribute speaker duties between more than one amplifier. Identifying which speakers are powered by the head unit and which are powered elsewhere helps avoid incomplete upgrade plans. Confirm the exact audio package and supported channel arrangement before selecting amplifiers or deciding which original components to retain.
The newer ZEN-F25 family addresses supported later Ford applications. NAV-TV publishes different kit revisions, so match the exact kit number, hardware and current instructions. Check the required harnesses as well as the main interface. A general product-family description is not enough to establish the contents or behavior of a specific revision.
Motorcycle integration with ZEN-H PRO
NAV-TV’s ZEN-H PRO, NTV-KIT1022, brings its integration approach to selected Harley-Davidson applications. The published compatibility list includes specified CVO, Road Glide and Street Glide model years. The interface provides eight low-level analog output channels and incorporates an eight-channel digital signal processor.
Documented adjustments include time alignment, phase inversion, crossover selection, gain and equalization. These tools give an installer control over how the speakers work together after amplification is changed. The product description also addresses retention of factory functions such as volume, fader, balance, chimes and EQ presets. Confirm the motorcycle’s actual year and infotainment equipment before assuming compatibility from the model name.
Camera interfaces for factory displays
Camera integration is another major NAV-TV category. The UCTv2, NTV-KIT762, adds two camera or video inputs to compatible factory 8.4-inch uConnect systems. Its fitment chart identifies particular vehicles and radio versions, showing why screen size alone cannot identify the right interface.
A similarly named product can have a very different restriction. The UCTv2-W, NTV-KIT851, is documented for the all-new 2018 Jeep Wrangler with the 8.4-inch uConnect system and requires a vehicle without a factory camera. NAV-TV explicitly excludes the 7-inch screen and MyGIG radio for that kit. An existing camera is therefore a fitment detail to report, rather than an accessory that can be ignored.
Other packages include an application-specific camera as well as the interface. The ProMaster-Cam kit NTV-KIT602, for example, combines its interface with a center-brake-light replacement camera for supported ProMaster and Ducato applications. Check whether the chosen package includes the camera, required harnesses and mounting solution, or whether those items are separate. Camera images assist observation; the driver still needs to check the surroundings directly.
Smartphone and radio-replacement options
The SYNC2-CARPLAY interface, NTV-KIT1048, illustrates a different upgrade path. NAV-TV describes wired and wireless Apple CarPlay and Android Auto for selected Ford and Lincoln factory systems, together with camera and additional video inputs. Its listing notes that the auxiliary audio input must be enabled. Confirm the complete radio configuration and audio path before treating a vehicle’s age as proof of fitment.
For selected Porsche Cayenne installations, MOST-H.U.R. 955, NTV-KIT155, works in the opposite direction from an amplifier-replacement interface: it supports an aftermarket radio while retaining the factory fiber-optic amplifier. Its listing includes specific steering-wheel-control limitations for replacement radios. Plan around the exact new head unit, original audio package and desired retained functions rather than assuming every control will carry over.
Plan setup and final testing
Read the installation instructions before booking the work. Confirm programming needs, power and ground requirements, output routing and any software used for setup. For example, the ZEN-25 manual discusses shared power and grounding with the aftermarket equipment and includes troubleshooting guidance for systems using another DSP. Those details belong in the installation plan.
Before trim panels are refitted, test music, calls, navigation prompts, warning sounds and the supported volume and fader functions. For camera work, check activation and image orientation. Keep the exact kit number and revision with the installation records. Products in this guide illustrate NAV-TV’s documented range; they do not establish current 12 Volt Outlet stock or availability.
