Garmin Zumo models – specialist sat nav for bikers. There’s not any Zumo voucher code discounts around at the moment that we’re aware of, but you can buy a ‘nearly new’ 590LM from Amazon Warehouse. Also, ebay has some good deals for brand new models. And, of course, Amazon often sell far cheaper than the rest! See our ‘Best Motorcycle GPS’ page (from the sidebar or dropdown) for a comparison chart of the different Zumo models.
