If you do or dont use the patches, i always recommend using the free StarPatch loader ( instead of Meades ASU ) to do firmware updates
as it is much more robust than ASU and gives better diagnostics.

All the latest patches are on this site as well
( note buying the GPS lump costs money, but the loader application is freeware )
