TSB:Abnormal Entune/Navigation Operation for Display Audio (Non-HDD Type)

Toyota just released a service bulletin T-SB-0030-12 for the Prius V (and other Toyota vehicles) on January 27, 2012 as follows:

Abnormal Entune/Navigation Operation for Display Audio (Non-HDD Type)

Some 2012 model year Toyota models equipped with a Display Audio Navigation System and Entune may exhibit one or more of the following conditions:
• Vehicle orientation slow to update after vehicle startup
• Five Bing search results are not all displayed on the map
• Voice recognition destination request does not provide feedback
• Voice Recognition for POI search displays "Function not available" message
• "Car Multimedia" device name cannot be changed


The resolution requires the dealer to simply update the software to version 1.8.4 with a USB drive plugged into the vehicle USB port on the dash.

This update is now a step in the 2012 pre-delivery service check list for the Prius V so existing inventory should be updated before delivery.

However, I just received my Prius V last week and when I checked the software revision level (via the display menus), I still have an older software revision that needs to be updated.
