Garmin numaps (Europe) for Zumo 660,
This review is from: Garmin Nmaps - Full European Lifetime Map Updates for nuvi series (Electronics)
Having read other reviews I was a bit wary about downloading the maps. However, it all worked faultlessly. The only reason I gave it four stars rather than five is that it took about 2.5 hours to download the maps and then load them onto my Zumo 660.
Key advice from other reviews that I followed was a follows:
1. Made sure I was connected to a fast Internet connection
2. Logged on to the Garmin site
3. Attached my Zumo 660
4. Downloaded all software updates for my Zumo
5. Started the Numaps download and followed all the instruxctions from the software.
