I bought a new SD card, and then downloaded the update onto computer. I unzipped the file, did extract all and loaded that file on the SD card.According to the guys on BBC it is the correct file. I inserted the card in my console unit. Turn the unit on and nothing out of the ordinary happens, unit boots up like normal, no update. Just to see if anything is working I downloaded my waypoints onto card and the export worked fine. The unit will show the upload file on the card, but wont load it.
