Notice about AVIC-Z1 and Z2 Firmware Update for Lock-up and Freezing Issue.

September 14, 2007

Dear Valued Pioneer Customer:

Re: Free Firmware Update for Pioneer AVIC-Z1 & AVIC-Z2 to Address Lock-up/Freezing Issue

We would like to inform you of the availability of a free firmware update for the AVIC-Z1 and AVIC-Z2 to address a potential lock-up/freezing issue. Pioneer has become aware that a small percentage of AVIC-Z1 and AVIC-Z2 systems, especially in very hot temperatures, lock-up or freeze when powered on, such that the systems do not proceed further than the initial boot up screen.

If you are not experiencing any lock-up or freezing issues currently, there is no need to take action at this time because the one-time fix to resolve the issue will be available if an AVIC-Z1 or AVIC-Z2 later experiences the issue and because your system may never experience the issue. Importantly, this potential service issue does not pose any health or safety risk, and there is no risk of property damage.

To address this potential service issue, Pioneer is offering a free firmware update. If you would like to receive the free update, you may do so in one of the three ways listed below. Before obtaining the firmware update, you need to know whether you have an AVIC-Z1 or AVIC-Z2.

1. Download the free update to your computer from here; and burn the update onto a computer disc for insertion into your AVIC-Z1 or AVIC-Z2; OR
2. Order the computer disc containing the free update by calling Pioneer Customer Service toll free at 800-421-1404; OR
3. Call Pioneer Customer Service toll free at 800-421-1404 to arrange for your AVIC-Z1 or AVIC-Z2 to be mailed to Pioneer for Pioneer to install the free update.

There are separate firmware updates for the AVIC-Z1 and AVIC-Z2. Please only use the firmware update that corresponds to your model, as the firmware update for the AVIC-Z1 will not work for the AVIC-Z2 and the firmware update for the AVIC-Z2 will not work for the AVIC-Z1.

If you have any questions, please contact Pioneer Customer Service toll free at 800-421-1404.

Pioneer service representatives are available Monday through Friday, 9:00 a.m. to 7:30 p.m. (Eastern Time).

We sincerely apologize for any inconvenience this potential product issue may cause you, and we thank you for your cooperation and continued support of Pioneer.

Sincerely,

Pioneer Electronics (USA) Inc.
