Q: How is the system activated?
A: Double Press the "Home" button on your factory system

Q: How do I perform Street Navigation and Hema Map updates?
A: Map updates are easily performed with a Windows PC. The navigation computer will be mounted in an easy to access location. Instructions for updating both systems can be found under the downloads tab.

Q: What warranty does this system come with?
A: The hardware of your system comes with a 2 year warranty except for the SD card, which has a 12 month warranty.

Q: Does it interfere with any factory features?
A: If you do not have the navigation showing on the screen, then all factory features will remain as they are. Reverse cameras (if installed) will continue to be displayed when reverse is selected and Bluetooth phone calls can still be answered even if the navigation is showing on the screen. On this system we use a separate speaker for alerts and voice guidance. 

Q: What Point of Interest information is available?
A: The navigation system comes with over 750,000 points of interest built in, which includes petrol stations, restaurants, accommodation, parks and many more.

Q: What sort of voice guidance does the system have?
A: There are 3 options for voice guidance. A “TTS” (Text-To-Speech) voice will give you the most information and will announce street names, etc. A non-TTS voice will announce directions, but will not announce things like street names. Lastly, you can set the system to have no voice guidance by muting the voice. This is done by pressing the “Menu” button and then selecting the small “Speaker” icon that appears along the bottom.

Q: Do I need my mobile phone to be navigated?
A: No. This system is completely independent of any phone and it relies solely on GPS signal for navigation.

Q: Why is my GPS time wrong?
A: This is likely just a setting in your navigation. In the “Settings” menu, select “Regional”. Here you will be able to adjust whether the navigation system bases the time on your location or whether you want to set it manually (eg. GMT +10 for AEST). If your time is 1 hour out, there is also the setting for Daylight Saving Time which can be found here and adjusted if necessary.

Q: How can I change the voice?
A: Go to “Menu”, page across to “Settings”. Select “Regional” and then go in to “Voice Language” and change to your preferred option.

Q: Why are the speed limits or streets wrong (even though they have been the same for many years)?
A: It is a very difficult process to map with 100% accuracy and the map provider does make use of end user information. Sometime things change (eg. new school zone), sometimes the data is incorrect. Please ensure that you have updated your navigation to ensure you have the most up to date content. 

Q: What type of system is the Hema 4WD Nav operating on? 
A: The Hema 4WD Nav is an OziExplorer based system with the Hema Maps User interface which is designed to make it easy to operate the OziExplorer.

Q: Can I add my own maps to the Hema 4WD Nav?
A: Yes. You can remove the navigation SD card from the navigation computer (which should be mounted on the computer) and insert it into your windows computer and copy the map files to the "OziExplorer Maps" folder. Detailed instructions can be found in the downloadable user instruction manual under the Downloads Tab.
