At first launch NavTruck will run through a Truck dimensions wizard, during this process you need to add the dimensions of the vehicle you are driving. Within the NavTruck map data includes any restrictions on the road. NavTruck will compare your entered vehicle dimensions against the route to ensure your vehicle is suitable for the road. NavTruck will not provide any route which your vehicle is unsuitable for.

This is the unloaded weight as road restrictions are based upon an unloaded weight of vehicle.

NavTruck will never provide a route which guides you onto a road which is unsuitable for your vehicle. If you detour off the provided route onto a road which NavTruck recognises as unsuitable NavTruck will stop providing any directions and provides an on screen warning instructing you to find an appropriate exit from the road.

There are several reasons why it is not appropriate to provide instruction when on an unrestricted road.

1. NavTruck knows if a road is unsuitable it does not know the exact location of the restriction, it is therefore likely that the actual restriction is nearer than the next available turning, but NavTruck will not know this and would therefore provide the driver instruction driving into the danger it is suppose to avoid. This is unacceptable.
2. If the road is not suitable then the driver will need to make a decision on the best outcome, by stopping the navigation this is the most appropriate way to stop the driver using the navigation to guide them.

NavTruck is designed not to instruct drivers to perform u-turns as it is very difficult for a truck to turn around. NavTruck will try to find an alternative route instead of instructing the driver to turn around. If an alternative route that is less than 20 miles is not found, only then will the driver be instructed to perform a u-turn.

NavTruck contains both speed limits for automobiles and for trucks. If NavTruck has the Truck speed limit for the road currently being driven this will show as the default, this will show a truck image: If the current road only contains the automobile speed limit this is shown as above but without the truck image below the limit.

There are two possible reasons for this:

1. Firstly you will need to ensure that the dimensions and load type are correctly set, if these are not correct NavTruck does not know to avoid the correct roads.
2. Unfortunately NavTruck does not contain 100% of all truck restricted roads, it is therefore possible that the road has not been mapped as truck restricted.

NavTruck routes are based upon the truck dimensions and any hazardous materials you may be carrying and uses these to eliminate unsuitable roads.

Yes, text to speech is included as standard on the NavTruck Truck product.

North America, Canada and most Western Europe countries have good coverage of truck restricted roads, but it is not possible to guarantee 100% coverage of all truck restrictions anywhere.

Yes NavTruck does work with Live Traffic service, please note though that traffic information is only covered for major roads it is therefore likely that any traffic incidents reported will advise the driver to leave the major road and drive onto minor roads. Minor roads may not be suitable for large trucks.

NavTruck contains many standard POI's along with additional categories specific for Truck. These include Weigh stations and Truck specific fuel stations.

Safety camera updates are sent out and provided via the 'News & Updates' button within the NavTruck app.

No, because safety camera speed restrictions in general are not set to Truck speeds.

Unfortunately map upgrades are not available for NavTruck.

Your iPhone has a built-in GPS receiver which allows it to pinpoint your location accurately on the map. It may take more than five minutes to acquire an accurate GPS position or 'fix'. Your iPhone or iPad 3G will also use your mobile Internet connection to help initially determine your location.
Please note that NavTruck will not provide turn-by-turn guidance until you have a full GPS fix.
When you start NavTruck your position will usually be quickly displayed using the iPhone's mobile Internet connection, however it may take more than 5 minutes to get a full GPS fix
It may take several minutes to get a full GPS fix. There are a number of factors which can affect an iPhone's ability to acquire a full GPS fix:

• Make sure that your iPhone has a clear view of the sky. This will help you get a GPS fix quicker
• Ensure that the iPhone's Location Services are switched-on. On the iPhone, Settings > General > Location Services. Make sure that the Locations Services switch is set to 'ON' Also, look for NavTruck in the list of apps below and make sure that it's switch is set to 'ON' too
• Use an in-car windscreen mount. Customers report that iPhone GPS reception can be improved by securing the phone in-car using a windscreen mount. NavTruck is also compatible with some 3rd party GPS car kits, including the TomTom iPhone GPS car kit
• Take your iPhone out of its case. Some customers have reported that that cases can sometimes interfere with GPS reception. You may wish to try removing the case when using the iPhone for navigation
• Make sure you have a mobile internet connection. Although NavTruck's maps are stored on the phone, not downloaded per trip, the iPhone may need to use the mobile Internet briefly to acquire an initial GPS fix. If you abroad, you may need to enable data roaming on your iPhone briefly in order to get a GPS fix. Once you have a GPS fix you can then switch-off data roaming.
• If you are still unable to get a GPS fix within 5 minutes, try powering off your iPhone by holding the power button down then swiping the red POWER OFF bar to the right. Then switch the phone back on and try again.
• Synchronise your iPhone with iTunes regularly. There is some evidence that this can improve GPS performance
• If you have tried all of the above, a final option is to completely uninstall NavTruck from your iPhone and re-install it through iTunes.

If none of these suggestions help and you are unable to ever acquire a GPS fix there may be a problem with your phone's hardware, and we would recommend contacting Apple.

There are a number of ways in which you can adjust the routing settings to suit your preferences. You can create a personal routing profile by selecting MENU | SETTINGS | ROUTING PROFILES | NEW, then name your routing profile and select OK. Choose the type of vehicle you will be driving for this routing profile then select > and you can then customise whether to avoid or favour specific types of roads and also set the speed that you would usually travel at.

Estimated Time of Arrival's are based on a number of factors including the road speeds, the roads you are driving and the routing profile you have configured. Estimated Time of Arrival's are an estimate. If you get stuck in traffic or are slow moving we cannot foresee what delays may be ahead of you. Estimated Time of Arrival's are updated from your current position to your destination based on no other delays.

If your headset fully supports A2DP and the Bluetooth Audio Gateway then we will support this in NavTruck.

When the iPhone is connected to certain car kits, headsets or speakers the accessory may take control over screen dimming. Unfortunately at this time there is nothing we can do to stop the screen dimming.
