Updating garmin satnavs

Cheaper models have resistive touchscreens, which flex slightly when you push them, are less precise and don’t provide such clear image quality.

From collision warnings to black-box video recorders: your satnav doesn’t have to be a one-trick pony.

Some display the current speed limit, or act as dashboard cameras, recording video footage that you can use in the event of an accident.

The big manufacturers have honed their basic route guidance for years, and there’s little to choose between the standard displays.

You tell it where to go and it will find the best way of getting you there.

Even basic satnavs now come with lifetime map updates, so you’ll always be guided on current roads, and you won’t end up being the driver who followed their satnav into a lake because a road used to be there.

One of the most useful features, if your car doesn’t already have it, is a Bluetooth connection.

This can make all the difference when you’re surrounded by traffic in an unfamiliar situation.

Speed camera warnings are billed as alerts to warn you to take care on stretches of road that are so dangerous that they have had to have speed cameras installed.

The device will usually beep as you approach a camera – also serving as a handy reminder to check your speedometer. Putting another screen in your car could be a recipe for distraction, but the best models come with voice control to minimise how often you need to use the touchscreen.

I never really worried about small changes to the road network. And don’t forget the time they take to download and install – it’s probably longer than the time you’ll take figuring out the correct route!

If I came across an unexpected mini-roundabout or toll road, I figured out a way to get to my destination. On the other hand, Tom Tom claims ‘on average 15% of roads change every year.’ This sounded like a lot, so we asked Tom Tom to explain the figure. Maybe you live in a modern housing development where new roads and roundabouts have been recently added. However, it is worth taking advantage of your sat nav’s ‘latest map guarantee’.But in my view, paying for map updates every year is probably an unnecessary expense.
