How to Update a Sat Nav
Your sat nav will include current maps and software when you purchase it. However, over time, more up-to-date maps and software may become available.
Updating your sat nav means it will be able to navigate the quickest and most convenient route, as well as show up-to-date information on things like petrol stations, shops and hotels.
Each sat nav and GPS device is different, so the advice given here is intended for general information only. Please check with your sat nav manufacturer for specific instructions.
When Should I Update My Sat Nav?
Many sat navs include one free map update, which can be used in the first three months of ownership. It is worth using this free download in case an update has been released since your unit was built.
How often you should update for your sat nav depends on its usage. If you are a frequent driver who makes regular long distance journeys, then you will want to update the maps more regularly than if you make infrequent, shorter journeys. As a guide, Halfords would recommend that you check for updates every six to twelve months.
If you are currently looking for a new sat nav, it's worth considering a model that comes with lifetime map updates. These include free map updates for the life of the sat nav, helping to avoid further payment in the future.
Types of Sat Nav Update Available

- Map Updates - These can be purchased direct from the manufacturer, either on an SD card or as a download direct from their website. Map updates will bring the current mapping on your device up to date, to include new roads, routes and points of interest.
- Additional Maps - These are available to purchase to add to your current maps. You can often buy maps either by country or by continent. Visit your manufacturer's website for more details.
- Software Updates - These keep your sat nav working effectively. They are usually free, and again are available on the manufacturer's website. It is worth keeping your software up to date, especially as this updates satellite locations, which will help your device find its position quicker.
How Do I Update My Sat Nav?
To update your sat nav or GPS, connect it to your computer and go online. Visit your sat nav manufacturer's website, where you will be able to find map updates available to buy and download. You may need to install a program onto your computer to enable the download.
Alternatively, some devices can be updated using a SD card, which can be bought direct from the manufacturer.
Specific information on how to update a sat nav should be found in the instructions that came with your device.
What Will Happen If I Don't Update My Sat Nav?
Over time, if you don't update the software, your sat nav may prompt you that the mapping or software is out of date and needs to be updated.
This is nothing to worry about, as the device is just reminding you that there might be more current software available.
Although it is a good idea to keep your sat nav updated, this does not mean that your current mapping is obsolete or that there is anything wrong with your device. You can continue using your sat nav as usual until you have the chance to update it.
