  • Gracenote Update

    Gracenote database updates contain ID3 tag meta data to show new artist, album or/and track info of the music charts. Since the database on the devices is static, artist meta data become outdated. Or in other words, the update provides a refreshed database covering new albums, new artists and new songs. The Gracenote update thus refreshes the content of the latest music charts.

    Usually there is one Gracenote database update scheduled per year.

  • What conditions must be considered for device installation of the Z-N720?

    The Z-N720 is designed for normal vehicles offering a 2-DIN mounting slot. That means for the physical mounting of the Z-N720, a car specific mounting kit that fits into the target vehicle is required. Depending on vehicle brand and model, different 2-DIN mounting kits are available from a range of accessory suppliers. On top of this, there is a selected range of “OmniMask Kits” available, that offer improved vehicle integration aesthetics.  For the current range of OmniMask kits, please follow this link: http://www.zenec.com/en/products/naviceivers/naviceivers/z-n720/omnimask/

    I cannot eject the CD or the DVD – the Eject button is missing on the device?

    Disc Eject function is provided by the “MEDIA” key on the front panel of the Z-N720. Press and hold “MEDIA button for 3 seconds, to eject a CD or DVD.

    Do I need to adjust the “Antenna Supply” setting in the setup menu?

    The Z-N720 contains a phantom power supply, to feed active FM antennas.

    Antenna phantom power factory default is OFF.  The use of an external phantom power supply is not recommended by ZENEC, since the self protection logic of the tuner pc board will enter protection mode when both external and internal phantom power supplies are set to ON (accidentally).

    For vehicles that are equipped with a passive FM antenna, the power supply must be set to OFF – for active antennas, the correct setting is ON. So this particular setting depends on the vehicle itself and the antenna present in the car. ZENEC recommends an on site check with the dealer where the vehicle or device was purchased. The FM performance is – to a certain extent – dependent on the FM antenna type, its vehicle mounting location and the correct settings in the device menu. If you have questions on any of these points, please consult your dealer or let your dealer verify related settings for correctness. 

    My Z-N720 has a problem with FM RDS radio reception quality. What can I do?

    Aside of the points mentioned above under “antenna supply” you should check if your device has been properly set up for best FM reception. It is recommended to check the following settings in the setup menu, since this will affect general reception quality and in some cases, also the quantity of FM stations found with auto-scan:

    Adjustment options in the “TUNER” source mode:

    AF ON: With AF turned ON, the device will automatically search and select the best available FM station (for stations that provide Alternative Frequency options).

    LOC or DX: To choose local radio stations, or stations that are further away. With LOC chosen, only nearby stations with good / strong FM signal level are found with the auto scan.

    If the radio reception does not improve with these measures and adjustment options, you should visit your dealer and ask for assistance. In some cases it may require an antenna amplifier to be installed to improve signal strength.

    Does the Z-N720 offer steering wheel remote control integration?

    If your vehicle is fitted with a steering wheel remote control option, chances are quite high that a car specific IR-code based CAN or Stalk-interface option is available from an accessory supplier. Such “universal” CAN/Stalk interfaces will usually support Vol up/down, track changes and (BT hands-free) telephony buttons of the steering wheel. Please consult the dealer where your  ZENEC device was purchased from to discuss potential CAN/Stalk interface options and  functionality.  

    Most OmniMask Kits contain the accessories required for mounting and connection of the Z-N720, which includes the car specific CAN/Stalk-interface as well.

    How does the TFT brightness adjustment and the day/night HMI switching work?

    The device features a light sensor. Three different options to control the screen brightness are available. In the setup menu under Video / Picture on the second page, you will find the following settings: Brightness: Navigation / Sensor / Car

    Choose “Navi” to allow the GPS system to set brightness automatically over day / night signal of the GPS system.

    Select “sensor” to allow the screen brightness adjustment via light sensor embedded in the device. Note that the sensor is insensitive to fast changes of brightness on purpose, the delay reduces unwanted screen brightness changes (for example during device operation or driving through avenues with trees etc.).

    Select “Car” to adjust the brightness according to signals present in the CAN net of the vehicle itself. 

    Note that if the GPS signal is day / night switching enabled, the sync process may take roughly 20 seconds after device start up before it has an effect. This can also be affected by location and terrain.

    How does the day / night switch work for the HMI: The factory default is set to day / night switching controlled by the GPS navigation system. However, it is possible to adjust this function manually. If the GPS signal-controlled auto switching is not desired, it can be deactivated in the Navigation Pane of settings (NAV> More> Settings> Map Setup> Color> Day / Night / Auto).

    I can not understand the navigation software update process, is there a ZENEC Support function that could help me?

    Yes, there is a ZENEC support team. This team mainly supports our re seller network, so to assist end users we have provided  instruction videos for the update process and these are found by going to our ‘Support’ page and clicking on your model and then select “Navigation Software’ and scroll down to the video. 

    Why do I need software updates and where do I find them?

    To keep your device up to date, ZENEC  frequently releases software updates for models to add new functionality, correct software issues and improve stability and reliability. 

    Software updates can be downloaded from the ZENEC Australia Support Knowledgebase. Go to “Support” and then select the Universal Z-N720 Vehicle Specific Folder.  Select the “Software Updates”.  Do not install “updates” from other unknown sources, as this might damage your device.  Depending on your device model, you may find MainSystem SW Updates, CAN-System Updates, or Gracenote and Bluetooth updates on our ‘Support’ page. To avoid damage to your device, please make sure you follow the update instructions carefully.

    Do not download software packages from third parties or other unknown sources on the internet, even if they claim “it was made for ZENEC”. External software developers do not know the system design or the actual system software configuration. By installing software from an unknown source, your device can be irreversibly damaged. Warranty repairs for devices that are damaged by unauthorized software are not covered by the device warranty and repairing the unit may be expensive depending on the damage done.

    My ZENEC device navigates incorrectly, street names aren’t shown, route re-calculations are triggered on the device.

    We use maps from the market leader ‘here.com’ for Australia and New Zealand.  It can happen that occasionally incorrect map data may cause a navigation error. We recommend that this should be reported directly to ‘here.com’, and this will enable them to correct their mapping data.

    Why does the Z-N720 reboot, when I start the engine of my car?

    To protect the device electronics from under voltage conditions and resulting malfunction of  modules inside the device, the ZENEC mainboard and the MCU constantly monitor the power supply voltage via sensors. This will trigger a shut-down (and reboot) if the supply voltage drops below 9 V. The automatic voltage sensor process avoids faults on the device operation due to incomplete loading of software data. This is a device self protection process and is not a defect. If the device does reboot after engine start from time to time, we recommended you see your car dealer for an inspection of the  battery condition, and also if wires and contacts are corroded that can cause supply voltage drop below 9 V.

    What do I need to consider for the use of microSD cards?

    The microSD card reader on the front side of the Z-N720 device is reserved for the navigation SD-card operation and data retrieval exclusively. Avoid removing the microSD card from the device when the sat nav application is running. Playback of video or audio files stored on normal microSD cards, using the microSD-card slot on the front panel is not possible.

    The USB hub keeps changing the drive indication (over optional accessory Z-EACC-HUB)?

     It may happen, depending on the assignment of USB memory devices connected to the USB hub, that the media drive indicator does change the address of drives assigned before, due to dynamic assignment of drive letters by the system.

    If you have problems with file playback from USB sticks, make sure that the USB media is formatted correctly before use. Windows Vista, Windows 7 and Windows 8 give you the option of a quick format or full format process. For any problems encountered with USB sticks, applying a full format is recommended. Make sure that the checkbox at formatting options -> Quick format is not enabled. Also make sure, the FAT32 file system has been selected. Do not use NTFS, HPFS and EXTFAT file system / format settings.

    Content on USB data carrier is not recognized even after successful formatting?

    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. There may be different reason for this to happen, such as usage or storage of data carriers and problems occurring at the initial format process.

    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 data carrier of another brand or manufacturer.

    What do I need to consider for audio playback from USB source

    Make sure your USB data carrier has been formatted in FAT32 – prior to use. Zenec recommends the use of high quality USB sticks only. Study the corresponding key features of the ZENEC device, for supported USB flash memory data carriers. Note that the USB connector of the device is current limited to 1000 mA maximum consumption. In most cases, external hard disk models will exceed 1000mA and thus, Zenec does not endorse the use of such products. Additional info for troubleshooting of USB flash memory devices and MP3 playback.
