The size of your screen is very important when buying any GPS unit as it’s the difference between being able to read the maps that are telling you where to go and not. A Big screen size also means that you can have more than one thing on your screen at the same time and still easily be able to see it.
Imagine being able to have a 3D Map with direction showing you where to go on one side and on the other an overview image showing the precise road layout or on one side of your GPS, your direction and the other, a list of points of interest that could be worth a visit as you travel along your route. All this is possible if you have a large screen, however a large screen does not always mean better.
A Large screen needs to have the support in place to ensure that you can actually see the device. The screen needs to be high definition, with a super sharp image and good color schemes otherwise you will have a great screen, but not be able to see it especially if you have any direct sunlight on your machine.
Our advice is that you choose the biggest screen that will fit into your car. A big bad screen is better than a really good small screen. It may not be perfect, but at least you will have. Make sure that when you buy a big screen that you also buy a Named Brand as these will usually perform better over the longer term. Popular Brands of In-Built GPS Units include, Alpine, Eonon, Erisin, Kenwoood and Ouku.
