I ordered this Liftime update, although I have read here by some that they had problems with activation. Of course I wanted to try. Lo and behold, I had no problems. Since I already had an account at Garmin, I needed the data only complement and already has the update be installed on my Zumo 660. Meanwhile, two small additions to came ... also problem. My recommendation: Buy and install .... a little cheaper than directly from Garmin. Go then!
