Type08 of 2011.21 is equivalent to Type07 of 2011.20, so is for Nuvi 2xx5.

The size reduction in 3790T is due to smaller ASR files.

Type07 of 2011.21 is a newly added type which contains high resolution JCV (hence the big size) and 3D building. Almost like Type06 for 3790T but no ASR and G2S. Not sure which model this is for?
