Done! On January 3, 2011 came the long-awaited, but, unfortunately, a small firmware update for the nuvi 13xx and 14xx series (region file only) - software version 4.90
Changes made from version 4.70 to 4.90:

* Fixed issue with junction view files not updating properly during a map update.
* Fixed issue with audio intermittently not working.
* Fixed issue with Australia Topo map turning off the unit in certain conditions.
