The market for integrated satellite navigation in vehicles has evolved enormously over the last 15 years.

For a while they were an essential option on premium cars, and could add up to £3,000 to the value of a used model.

This was never the case on mainstream models, and as portable navigation systems became more affordable and widely available, the value of an integrated sat-nav in a vehicle reduced.

One of the biggest providers of portable navigation systems has been instrumental in offering a half-way house with some manufacturers. Renault was the first manufacturer to offer an integrated TomTom navigation system, and Toyota and now Mazda are among those that followed suit.

Out Mazda6 has TomTom touch-screen navigation (with additional controls on the centre console should they be easier to use), although effectively an option, our car has the designation Sport Nav, which means a specific value can be attached to a sat-nav equipped car at defleeting time.

According to the Fleet News running cost tables, the addition of navigation results in a £150 uplift in value at four years/80,000 miles only a quarter of the cost of adding navigation, but it could perhaps save money in ensuring drivers are led directly to destinations, alerted to traffic problems and don’t get lost.

I discovered one of the fun aspects of the system when exploring the various settings as I discovered that English navigation instructions are available with a variety of accents. For example, James is Australian and has a colourful turn of phrase.

Upon reaching a destination he says: “You have reached your destination. Windows up, grab those sunnies and don’t let the seagulls steal your chips.”

Not a dealbreaker, but after a long and tedious journey it could help lift the mood.
