A naive question: could some of the inter-tile routing problems be
caused by the lack of an overview map?

Could it be that Garmin falls back to the larger routes defined in the
overview map for longer distances, thus avoiding the intervening tiles
completely?

This is pure speculation; I have no evidence to support this. But
could this make sense?

Cheers.
