I have indulged 300 for my 3 year old Garmin NĂ¼vi a map update. Although delivery was as always without any problems, but the product is the problem. Every time I want to enter the unlock code for maps, freezes me my computer, there's only off yet. Although computer is not the newest (IBM Thinkpad Centrino 1.6GHz), but he will drop just at the GARMIN software from. a few days later: Meanwhile my activation succeeded, after many hours repeatedly unsuccessful efforts. The procedure of activating the cards should be revised by GARMIN urgently .. (Note to other frustierte Updater: When "activation code has already been entered" (or something like that) comes, click on a button next to it to download, so it worked for me - I do not quite logical, but the main thing it funzt)
