If you’re lucky enough to own a white Lotus Esprit like the one from 1970s Bond flick The Spy Who Loved Me, then Garmin’s latest satnav will be perfect for you.

Garmin's Nüvi 500: features nautical mapping

That’s because the Nüvi 500 includes – in addition to bog-standard car navigation – directional capabilities for walking, cycling and, yes, boating.

For example, should you be punting down the Thames and forget which side’s port and which is starboard, then simply switch the Nüvi 500 over to boating mode. The device will provide you with everything from “detailed chart-specific information, spot soundings and intertidal zones” to information about “wrecks, port plans and restricted areas”.

Sadly, sailing charts are an optional extra. However, the unit’s waterproof 3.5in touchscreen will come in handy, in case the tide suddenly turns. The satnav also boasts a compass page and track log.

Should you also fancy on overland trip down memory lane Stateside, Garmin helpfully includes a historic Route 66 map guide that spans the highway from Chicago to Los Angeles.

The Nüvi 500 will be available in September for £300 (€377/$600).
