1. Display screen size and look
The screen size of your GPS unit will affect the price, with larger options costing more. A five-inch screen is currently the average for most devices, but you can save yourself money if you opt for something smaller. You may even find a compact model fits your needs better, particularly if you intend to fit the system to your windscreen – you don’t want the device blocking your view of the road!
2. Maps and Updates
Many GPS technologies come with a full set of maps, but due to construction works and new roads being built they won’t stay up to date forever. As such, purchasing a GPS device that has adequate map and update features can be extremely important. Check what the update policy is for your intended GPS before buying, with some models charging for updates, which can prove expensive over time.
