Hi, I now have 2 ttg bought 1gig sd cards for both and the maps for Europe. I installed them on one sd card and it asked me for the activation code which I did and it worked ok. Now, when I took the sd card out and put it into the 2nd ttg it asked again for an activation code and when I entered it again it would not work. Do you have to buy a set of maps for each ttg?

Yes. The agreement is for one unit only.
