Interesting development. Garmin GPS's always sucked at pre-programmed turn-by-turn routes, not sure if Google Maps update will address that. A friend went on a trip to Ecuador a couple of years ago, I helped him figure out how to download detailed Google maps, a rather time-consuming task then--one needed to select an area that was not too big otherwise smaller roads not included. Garmin's newish Edge Touring still has problems with pre-programmed TBT, signalling that they've essentially given up on that niche.
