Can't seem to win here.

The Indonesia (SG&ML) version allows postcode search will will not route correctly (gives up). It only supports gmap3d.img after deleting the original locked maps. I can get it to pick up any map if I rename it to this file.

The US 2.00.19 routes correctly but will not allow local searches (postcode etc). It will find any map using various names once the folder is chmod 777.

I haven't tested the Western-map version, fingers crossed (downloading now).
