Choosing the right maps for your sat nav
Each GPS sat nav comes with a selection of maps, either pre-installed or ready to download.
Not all sat navs have a large storage memory, so maps may need to be downloaded when you need them. Additional maps are usually available for a small fee.
Updates for your sat nav
Most sat navs come with free lifetime map updates. Updates can be downloaded from the manufacturer's website and installed via a computer, or direct to the sat nav if it's Wi-Fi compatible.
What are truck sat navs?
Truck sat navs are different because they take the length, width, height and weight of your vehicle into account when planning your journey.
This will help you avoid low bridges and restricted roads. They can also help you to find places where you can park your vehicle overnight.

Sizes from 4 - 8.9 inches are available. Larger screens are easier to read and have more room to use the touchscreen, but take up more space. When not in use you should protect the screen with a sat nav case.
