HDD Navigation System: Notes

The Acura TL uses a hard disc drive (HDD). The HDD system improves route calculation and POI searching time, as well as these additional functions:

• Ripping music to the HDD with on-board CD database (CDDB) 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.
• Seethe Owner's Manual or the Navigation 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 .

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 ECM/PCM via F-CAN.

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