WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.

The 2009-2010 TL uses a HDD (hard disc drive) instead of a navigation DVD The HDD system improves route calculation and POI searching time, as well as these additional functions:

Ripping music to the HDD with on-board CDDB (CD database) information provided by Gracenote
Clients can save their personal pictures to the HDD and use the images as wallpaper when they are not using the navigation system
See the owner's manual or navigation system manual for more information

HDD updates include the latest map info, POI DB, and CDDB information The yearly update is available on DVD that is loaded onto the HDD When you order a reman unit, the latest software is loaded onto the HDD If a client wants to order an update, see ordering an update navigation DVD (see ORDERING AN UPDATE NAVIGATION DVD )

The Gracenote CDDB is updated quarterly Clients can visit www.acura.com and download the latest update

The HDD shuts down to protect itself from damage:

If the audio-navigation unit internal temperature is 183 °F (84 °C) or higher
If the atmospheric pressure below about 9 psi (62 29 kPa) The atmospheric pressure signal from PCM via F-CAN

Warning of the temperature and the atmospheric pressure is displayed on the navigation screen as an error message
