In general, it might not help anyway. Consider a route that goes due north/south, close to the tile boundary. If it weaves slightly east/west and back a few times, it will cross tiles quite a lot - even more so if all the tiles are aligned.
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.
