I don't want to disillusion you but...my 'Edge Touring' came with the Garmin Maps pre-installed, it hasn't stopped it from being troublesome on occasions over the past 12 months of ownership. IME, if its just recording rides it works OK, its when its doing its job as navigating the way that things go awry.
Haha well typically the 810 I have is the opposite - haven't (yet - touch wood etc etc) had a problem when navigating, but it's tripped up often when I'm just recording a ride (even just the commute!).
