Correlation does not imply causation, of course, but after eight years of sterling service Emily the Garmin TwatNav started playing the goat after the factory updated her firmware fnarr and, moreover, fnarr. Now she reboots spontaneously at intervals ranging from five seconds to two hours, but only when she's connected to a motor-car's 12-vole supply. Which, given that her battery is as decrepit as this Unit, renders her Unfit for Purpose chiz. Therefore Garmin is a bunch of bastards.
And Garmin* don't sell a TwatNav with UK, Europe and North America maps any more, no, you have to buy the UK & Europe one and then fork out MOAR wonga for Leftpondia onna SD card. I am holding off buying a new one until the Coronalurgi has been vanquished and I am once more able to terrorise the “gas” pumps of USAnia with lack-of-ZIP-code-related Bad Swears. I think you can get one Over There with the map arrangement the other way round but it'll probably end up twice the price if you order it from the Mega-Global Big River Corporation of Seattle, USAnia's FOREIGN operation. Therefore Garmin is a bunch of bastards.
