This year’s Auto Express Product Awards has revealed the gadget most British drivers couldn’t live without – their sat-navs. Over a quarter of the votes cast for the Readers’ Award on autoexpress.co.uk named the GPS system as their must-have in-car gadget, beating even air-con and in-car audio systems.

Auto Express judges gave their top award for Product of the Year to digital radio specialist Pure for its revolutionary Highway 300Di – a clever new gadget that can add DAB and iPod connectivity to any in-car stereo.

Other winners included Essex-based Bilt-Hamber which won three awards for its cleaning products, TomTom for best smartphone app, Turtle Wax for best wax, Goodyear for best summer tyre and Continental for best winter tyre.

Steve Fowler, editor-in-chief of Auto Express, said: “With many car owners holding onto their cars for longer, keeping them pristine is critical to maximising their value at resale time. The Auto Express Product Awards is a chance for us to acknowledge the very best products out there for our readers to add value to their cars.”
