Garmin has released firmware updates.

Firmware updates for various 2012 and later models released this week.
Check your Device with My Dashboard or Garmin Express or Webupdater
Make sure to do the updates before the next Map Update.
It is very risky to do Map and Firmware together.
Firmware should always be done before Map.
Garmin will soon start to release 2015.10 Map updates for all countries.

I have a Nuvi 55 and, when connecting it to my PC and running Garmin Express this morning, it downloaded and installed a new firmware update - v.4.30.
