Another approach to this would be to create two map layers with two different TYP files. The lower, normal map layer contains the roads and the routing information. The second layer is transparent and only contains additional graphics for drawing on top of the map layer, e.g. colored bike route markings, tunnels, bridges and so on.
I thought about this, and I am going to try this approach next, since I don't have the time to implement the proposed extension of mkgmap by myself. But this solution will not help the POI problem. And the solution is also much less flexible: You have to decide before the map generation, which items shall be drawn on which layer. And you also need to decide before, how many layers you need. I think my proposal is much more flexible if you have different combination of multiple items (e.g. a street is on a bridge, has a cycle lane and is part of an relation) And I don't know, how the Garmin devices handle multiple transparent maps, In mapsource you always get only one map at a time.
