I'm not looking for a can of worms, but need the opinion of the people that know.
I can buy a Garmin Zumo 450, for the same price as a TomTom Rider 2nd edition. I need to know the advantages and shortcomings if anyone has that info.
I may go to a Zumo 550, but it seems to me that the TomTom has it all covered.
Thanks Carl
