Product review: Garmin Nuvi 3598 LMT-D

You could be forgiven for thinking that smartphones had made the average handheld sat nav extinct, but companies like Garmin don't seem to agree. Jon Reay tries the latest of its products to see if they can still compete.

What is it?

Garmin's poshest sat nav available – the Nuvi 3598 LMT-D, priced at a whopping £299. Brand new for 2013, it's a svelte looking thing, and has already been handed a RedDot design award for its pretty exterior.
