Garmin nuvi 56 LMT sat nav with free lifetime maps and traffic at Aldi. 5 Inch screen seems decent enough. I know a lot of people have smart phones that have google maps etc but some people like myself still have sat navs.
Seemed a good price when i went into my local Aldi that opened a second larger store in Leigh, greater manchester today. Not sure if this is nationwide or just my local store.
Plugged into my computer and within 2 minutes from downloading the software from http://www.garmin.com/express
i was downloading and installing updates.
