I am very happy to have learned that the software
Touratech QV I use for handling maps (calibrating, printing, ...) now supports the export of Garmin (Oregon, Dakota) bitmaps.
It also has a very good interface to GE so it is the ideal tool for me.
Maybe this (and the recently reduced prices for the Garmins) will force me to replace my Vista Cx by one of those, very probably one with the larger display. I will also be forced to carry a fifth more weight :/.
