Query: No signal in Rome

I installed the Garmin "City Navigator Europe NT" in my Garmin Nuvi 1260T. It appeared to be working properly, and provided maps of Rome, Venice and Ischia (a small island off Naples near Capri). I planned to use it walking around the streets. However, it was useless in Rome and Venice because I never got satellite reception. I did get satellite reception in Ischia. In Rome and Venice, where there are many narrow streets with buildings to block reception, I tried the navigator several times in piazzas that had fairly open access to the sky. It found no satellites on either narrow streets or open piazzas. My 1260T locks on to satellites in New Jersey, where I live, very quickly, much more quickly than 2 my older units (a Garmin Nuvi 250 and a Tom Tom). For me, the Garmin "City Navigator Europe NT" was a complete waste of money.
