I have a Garmin Nüvi 350 with software version 6.20. Is it possible to downgrade to an earlier version of the software version?
If yes is there an howto for on this forum?

The reason for the downgrade is that the nuvi 350 has a Fleet management interface mode and in this mode the nuvi 350 is able to accept waypoint infomation from an external source.
This is done together with a Gtrans cable.

To my knowledge the nuvi 350 is going into this mode by powering the nuvi from the cradle and connect the gtrans cable. I think and suspect that it has something to do with the software version, because I have read that after a certain version this does not work anymore....??
