I haven’t used TomTom since the first gen Rider back in 2008, it’s been a series of Garmins ever since. In interested in the new Rider 550 solely for the lifetime worldwide map update feature. I live half of the year in the US and the other in Italy so that would be a distinct advantage for me. I don’t see much mentioned here about TomTom so what’s the deal ? Are they reliable? How about the mapping software ( I currently suffer with BaseCamp so any improvement over that is a plus). Ok inmates, I’m all ears.
