I purchased a newly overhauled Garmin Zumo 660 from MNC Group which was rather slow in arriving. When it did arrive everything looked rosy. However when I tried to install the software on my laptop so that I could access the maps I was asked for a Product Key. There was no product key in the package which arrived and therefore I cannot access the map to to plan routes. I was wondering what my rights would be if this product key is not forthcoming?
