Garmin has released a very large firmware update for the 35x7 device:
Here is the Change Log:
Changes made from version 2.80 to 3.20:
Added support for the new HD Weather feature when using compatible HD Traffic cables. The feature is only available in areas where HD Traffic is available. In order to view localized text for this feature, you must download the latest translations.
Added support for the Environmental Zones feature for areas where the appropriate map data is available
Improved route comparison logic for alternate routes on the Traffic page.
Updates were made to use gray coloring for traffic events that do not contain flow data. This replaces the green coloring that implied traffic was flowing smoothly.
Improved support for Czech and Turkish TTS voices.
Improved Bluetooth audio volume.
Improved ramp support for the Signpost feature.
Added support for playing different audio tones to differentiate between static safety cameras and mobile safety cameras.
Added city, state, and country names to the points of interest search results list, where applicable.
Added Audio Mixer support to control the volume of speech recognition phrases. The Audio Mixer is only available when paired to a phone in hands-free mode.
Fixed a touchscreen lockup issue on 35x7 and 35x8 products.
Fixed an issue that prevented certain location formats from working correctly on the coordinates search page.
Fixed an issue that prevented certain routes from calculating correctly in Russia.
Fixed an issue where all Smartphone Link apps were available on the Apps page after deleting the phone pairing from the Bluetooth page.
Fixed an issue that caused the external power lost countdown message to display after the device had exited sleep mode.
Fixed an issue that prevented subcategories from displaying in the Michelin Green guide.
Fixed issues found in the Up Ahead feature.

Fixed an issue that would cause the Signpost feature to disappear when a notification displayed on the map.
Fixed several device re-boots that could occur while navigating with the Active Lane Guidance feature.
