The Zumo 220 is my third Garmin. I had a Zumo 550 which I sold with my Honda and still have a Nuvi 250, which although has a limited performance does at least work 100%. The 220 came with outdated maps but with a free update (only by internet) The new maps took around 2hrs on a 50MBit/sec connection to load onto my laptop.
Once I got it working, I found the following faults:
1. The maps would not transfer onto the 220.
2. I could not transfer routes from the computer onto the Zumo.
3. At some zoom levels, the roads and towns disappeared, only to reappear at the next zoom-out.
I have had none of these problems with the Zumo550. That had other problems whioch is why I sold it with the bike. As far as support from Garmin is concerned, the least said, the better.
To sum up, my device was junk, so I sent it back. Some users seem to be happy, so it seems to be the luck of the draw. All Garmin devices can now only be updated by internet. If you don't have the fastest connection, forget it.
