MSN Software Update for Nuvi 680

 

Using the web updater, this update is now available from Garmin. Installs to the Nuvi, then to the antenna assy upon connection. Takes 2 minutes to do. I will test it tomorrow. Hope it helps.

Changes from version 2.20 to version 2.30:
Improve reception while driving through areas of intermittent signal.
Acquire data faster when driving into a new coverage area.

Same for SP c580

It is the same update for both models. Haven't noticed anything yet. My reception and data acquisition remain the same after the update.
