Positioned for the European Aftermarket

The ZT-A34 PX5S is a 9-inch ultra-slim smart head unit aimed squarely at the European aftermarket — the region where DAB coverage, Italian-language UIs and strict installation depths decide whether a product sells or sits on the shelf. It integrates digital broadcasting, smartphone interconnection and professional audio processing in one chassis, and ships with European radio region, UTC+01:00 time zone and a 24-hour clock already set.

In short: a localized smart head unit that European distributors can put on the shelf and sell — not a generic Android tablet that needs a firmware project before the first customer.

Hardware Platform at a Glance

Underneath the slim fascia is a mature, stable hardware base: Android 11 system performance, a real automotive amplifier and a full set of expansion interfaces. Screen resolution and the MIPI/LVDS configuration are confirmed per project, which keeps panel sourcing flexible for different vehicle fitments.

A 9-Inch Screen with Dealer-Grade UI Customization

The 9-inch large screen gives radio, music, smartphone interconnection and vehicle settings an intuitive home. Just as important for resellers is what sits behind it: the launcher is deeply customizable, covering the home layout, secondary icons, boot logo, boot animation and function interfaces.

The 9-inch display — a canvas for dealer branding, not a fixed consumer skin.

Distributors can adjust the UI style to their own brand guide and build a differentiated terminal experience: one product line, many brand faces. The 165mm × 65mm mainboard is engineered for ultra-slim structures, so the unit meets the installation space requirements of a wide range of vehicles without dash surgery.

DAB Digital Radio, Tuned for Europe

Digital broadcasting is the anchor feature for European buyers, and the PX5S treats it that way. The W8-I2 DAB module delivers a high-quality listening experience with a dedicated DAB application interface:

Station logo display for instant visual recognition · customizable DAB interface that can follow a customer sample machine or brand style · DAB audio EQ adjustment routed through the same audio system as every other source, so the tonal signature stays consistent wherever the listener tunes.

The dedicated DAB app shows station lists, logos and a full-frequency scale — designed for European listening habits.

The complete signal path

Antenna → Fakra → DAB module → PX5S → DSP → amplifier → a short, install-friendly chain.

The DAB antenna connects directly to the vehicle antenna wiring through a standard Fakra connector, which keeps installation simple. The FM/RDS side runs on the Si4755 tuner with the European radio region preset and RDS program-service storage — song title and artist name displayed, station names stored.

CarPlay and Android Auto, Wired or Wireless

The TP300 version carries the complete CP/AA interconnection solution: wired CarPlay for a stable, low-latency link, wireless CarPlay for cable-free convenience, and Android Auto compatibility for mainstream Android devices. Drivers reach navigation, music, phone calls and the voice assistant directly from the head unit.

Wired or wireless — the phone takes over navigation, music, calls and voice assistant.

Two details matter for fleets and rental operators: independent volume control with customizable prompt text, and a deliberate decision not to configure generic screen mirroring — keeping the interconnection experience predictable and driver-focused.

A Real 4.1-Channel Audio Stage

Audio is where upgrade-market customers decide, so the PX5S runs the TDA7851L amplifier at 4 × 18W across front-left, front-right, rear-left and rear-right channels, with an independent subwoofer output that strengthens low-frequency performance.

FL / FR / RL / RR plus a subwoofer channel — enough drive for factory speakers and a path to external amplification.

Output hardware is upgrade-ready: 4 × RCA line out plus 1 subwoofer output at 4V RCA voltage, suited to external amplifier expansion in European upgrade audio systems. Subwoofer volume follows the main volume, so tuning stays simple for the end user.

9-band EQ with per-source memory

A built-in 9-band EQ can be tuned independently for DAB, FM, local music, Bluetooth music and phone interconnection, and the DSP interface itself can be restyled to the customer brand. The engineering focus is the subjective detail users actually complain about: volume consistency when switching between CarPlay, Android Auto, Bluetooth music and DAB, plus calibration of volume-step gaps so no jump feels abrupt.

Bluetooth and Dual-Band Wi-Fi

Connectivity covers both halves of the daily experience. Wi-Fi runs 2.4GHz and 5GHz dual-band, compatible with 802.11 a/b/g/n/ac, so maps, streaming and updates do not crawl on congested campsite or city networks. Bluetooth supports phone calls and music playback simultaneously, with the device name customizable for the dealer brand (default “JF sound”) and calls routed through the front in-car microphone.

Certification checks cover external-microphone call clarity, latency and car-kit detection, plus audio distortion and abnormality screening — the unglamorous tests that keep warranty returns low.

AHD 1080P Reverse Camera Support

Reversing safety is a rigid requirement in the European aftermarket, and the PX5S answers it with AHD 1080P camera support for a clearly sharper rear view. The hardware provides four video inputs covering AHD, TVIN and CVBS, and the standard RVC version focuses on essential reversing assistance.

AHD 1080P guidelines overlay — a clear, honest reversing aid for aftermarket camera upgrades.

European Localization, Out of the Box

From language to time format, from radio settings to UI, the PX5S is a head unit genuinely designed for European users — and for the distributors who support them:

Why Distributors Choose the PX5S

Digital radio. Smart connectivity. Powerful sound. That is the whole pitch — and the ZT-A34 PX5S delivers all three in one ultra-slim, shelf-ready unit.
