I recently ordered an update for my North American maps on my nuvi 255W sat nav (1C6279491) but I am don't seem to be able to download it.
No update shows up on Garmin Express, in fact my North American maps do not appear at all on there. Currently my Europe maps are stored on the nuvi itself and my North American maps are on a 16 Gb SD card installed in the unit.
I would be grateful if you could assist me with this as I am shortly going to be setting out for a holiday in the USA.
