Z-N328

AW: The Z-N328 is a 2DIN device model which will fit and work with most vehicles featuring an ex works 2DIN radio mounting slot.

AW: When the Z-N328 device is powered up the first time, a manual radio station search must be done by tapping on the “Scan” button. The scan may take up to 2 minutes to complete, depending on the signal strength and the amount of receivable the DAB stations.

AW: The Z-N328 features an integrated DAB+ tuner. For the reception of digital radio stations, an antenna supporting the DAB standard is required.
If your car does not offer a suitable DAB antenna, it must be retrofitted allowing you to enjoy the digital radio program.

ZENEC offers two DAB antenna models. The Z-EACC-DAB1 and Z-EACC-DAB2 are listed as separately available accessory items.

AW: During the development of the predecessor models Z-N326 and Z-N426, direct comparisons between matte (etched) glass and the clear high-gloss version under direct sunlight did clearly favor the glossy version to offer better font legibility for its higher clarity and better contrast levels. Therefore, the Z-N328 was conceived with glossy glass panel as well.

AW: If your vehicle is equipped with an OE steering wheel remote control it can be connected to the Z-N328. For this purpose, depending on the vehicle brand, model and model year, a vehicle-specific CAN/Stalk interface and a connecting wire to device (ZENEC ZEY-ZENECLEAD) is to be purchased separately.

AW: Yes, due to the glass type front the Z-N328 system has no opening for the microphone. Therefore an external Bluetooth microphone must be mounted to be able to use the BT based hands-free function of the device.

AW: The Z-N328 is designed as a system without remote control among other things, mainly because of the glass type touch panel, offering no opening for the IR eye.

AW: Mainly to give the customer a choice, depending on his personal preferences of use. Depending on personal requirements and frequency of use, it may be sufficient to use the smartphone’s own map App via the ZENEC Smartlink Direct function (Google Maps or iOS Maps are both suitable). The smartphone Apps may offer a route guidance good enough to cover sporadic router guidance use. For customers seeking a more professional navigation system offering a wealth of comfort functions, the Z-N328-SDFEU navigation package is the better choice, since it was specifically developed for the Z-N328 unit.

AW: During the navigation announcement, the volume of the announcement can be adjusted up or down directly via the horizontal volume slider of the Z-N328. Touch the VOL + sensor field during a route guidance announcement, to move the volume slider up or down. The last VOL adjustment value is retained.

AW: The displayed audio data comes from the device itself. The RealDash app can show device related audio info, such as iD3-Tag content when music is playing on the device – but also show vehicle / engine related info. For the latter, RealDash retrieves data via an OBD II dongle connected to the OBD port of the car. Compliant OBD dongles can be purchased from various vendors.

AW: RealDash offers two OBD2 communication optimization settings. Note that older vehicles may not support multi-PID data, leading to slow data transmission via OBD II port and stuttering RealDash graphics. These are the two available setting options.

Multi-PID Request
This setting works if you have relatively new vehicle with CAN bus. When this option is enabled, RealDash constructs a multi PID request command and when supported by vehicle, RealDash can receive multiple values in one reply. This will increase the data rate considerably. On older vehicles this setting may slow down the time to connect to vehicle and therefore it is disabled by default.

Request first PID reply
On some vehicles some requested information may be contained in several modules. For example engine RPM may be stored in ECU and TCU of the vehicle. Enabling this option will instruct the OBD II adapter to respond with first available value and not wait until all modules have responded to the request. This may increase the data rate in some cases.

AW: For BT devices that require a 4-digit pairing code, the code must be entered in the BT Settings of the Bluetooth Menu under “PIN?” before device pairing is attempted.

AW: To use Spotify, you need online access of the Spotify server. Therefore a Spotify user account is required to access the server via smartphone Hotspot (see Z-N328 manual).

Streaming audio content via smartphone hotspot is a “data transfer heavy use” which requires a suitable monthly subscription. For Spotify Streaming you need about 40MB per hour with “normal quality” (96kbps) and about 70 MB with “high quality” (160 kbps). So make sure your smartphone contract offers a corresponding monthly data quota. Exceeding the monthly allowable data volume usually leads to throttling of the data bandwidth by the provider.

AW: No, the Z-N328 is fine. The reason for the lack of audio output on the subwoofer channel with Spotify as audio source is a limitation of the Spotify SDK. This SDK targets smartphones, tablets and home audio devices and therefore does not have a dedicated subwoofer data channel. This means that the Spotify app on the device does not deliver any audio to the subwoofer line-out, which will then not provide any signal at the outputs.
If you want to drive an active subwoofer or an amp powering passive subwoofer(s), you can use Y-adaptors as workaround, splitting the signal from the front or rear RCA line-outs. If you do so, do not set a high-pass filter for the channel pair that splits the signal to the sub amp or active sub. Another option is to use the high-level signal from the speaker outputs to drive the active subwoofer or sub amp.
The restriction applies only to the subwoofer RCA line-outs but not to the internal amplifiers of the Z-N328, as the internal amps amplify and reproduce the full frequency range.

AW: ZENEC’s SmartLink Direct is an application software that allows both Android and Apple iOS based smartphones to be connected to the ZENEC device, for launch and control of the smartphone Apps via ZENEC touch screen. In order for Smartlink Direct to run in combination with your smartphone, it must be paired prior use. Please refer to the respective chapter in the main operating manual of the device or else, the special Smartlink Direct explanation page for the ZENEC models supporting this particular feature.

AW: The Z-N328 features an Android operating system. In order to ensure best resilience and highest operational stability but also to limit technical device support effort, a “closed” system has been realized, which prevents the installation of standard Android Apps.

AW: In order to keep the map content of your Navigation micro-SD card up to date, it is possible to update map database with a PC tool called “Toolbox” and Naviextras online update portal. On Naviextras you have access to free and pay type updates as well as other add-on’s. The separately available navigation package Z-N328-SDFEU comes with a 1-year map update subscription, allowing you refresh map content for the period of one year after first (GPS) activation at no cost. Within the given 12 month time frame, TomTom (map provider) would usually release two to three content updates (without guarantee).

For map updates, free content and various Add-on’s please visit Naviextras at https://zenec.naviextras.com

Disclaimer: The card update subscription duration can only be guaranteed in its entirety in conjunction with a new device which is put into service together with a new navigation card. For used devices with navigation packages purchased later, limitations apply because the date of the first use of device is crucial. Naviextras places a time stamp point on the device once first sat connection is established.

AW: This is caused by the TTS engine with Phonemes support, which is no longer provided by Nuance for Android OS based navigation packages but instead, comes from Pico. Anyone who is bothered by the pronunciation of a selected TTS voice should change to another non-TTS voice.

AW: Please note that ZENEC, for western and Eastern Europe coverage deploys digital map data by TomTom (formerly known as “Tele Atlas”). Even if you have recently updated the navigation map content it is still possible that digital map data contained is imprecise or even faulty in areas such as intersections, new roads and other places recently added. In such a case your device may provide you with incorrect routing instructions. Please use the respective TomTom tool to directly report errors to TomTom map share service: http://www.tomtom.com/mapshare/tools/

AW: The microSDHC card reader on the front of the Z-N328 is reserved exclusively for the operation of the GPS navigation system. Avoid removal of the microSDHC card while device is running, especially in active GPS nav route guidance mode.

AW: It may happen that the file system of the disk got damaged, or that the file allocation table of a data carrier is defect due to erroneous write cycles.

In such cases, you must format the data carrier again to make it work correctly.

Info: If the data carrier after formatting is still not recognized by the device, it may be due to an incompatibility of the disk controller chip itself. In such a case, you should use a different USB data carrier of another brand or manufacturer.

AW: The device is featuring two USB ports, which for the assigned functions do not reach fully redundancy. See the following list, what functions are covered by USB1 and USB2 ports:

USB1: Apple MFI (Made for iPod/iPhone)/ 1A quick charge function / USB media playback / EasyConnect / Wifi support (Dongle) / Device software update

USB2: USB media playback / Device software update / Wifi (Dongle support)

AW: Make sure your USB data carrier has been FAT32 formatted prior to use. Zenec recommends use of high quality USB memory devices only. Note that the USB connector of the device is current limited to 1000 mA maximum consumption. Since many external hard disk models will easily consume higher drive currents, Zenec does not endorse the use of such products.

AW: Go to Setup> Audio > Slider > Expert Mode> to access the „Equalizer“.

AW: Device allows to pair several smart phone showing up in the device list, while only one phone can be active.

AW: First, the password function should be set to “ON”. Before you can enter your own password, you have to enter the default password – 12345 – once.
