Need to replace your Acura's navigation disk drive?

This is a very common problem. The old disk drive eventually fails due to wear, excessive shock and temperature changes. If you have a bad disk drive you would be seeing any of several error messages on a blue and yellow screen, mostly Hard Disk reading error unformated (unformatted) Please consult your dealer, or incorrect Hard Disk and other odd behaviors it will exhibit such as locking up or rebooting every so often. Drives may fail at times and work at others until they finally crash. This is typical of any hard drive failure. Extreme hot or cold weather increase their failure rates.

I can send you a new replacement drive. The replacement drives can't fail like the original disk drives do and are a bit faster (recalcs 25-33% TL, 33-50% RL), they are solid state so no moving parts. I'll mail it the same day via USPS 2-3 Day Priority Mail and will send you the tracking number. Then just eject the old drive and slide the new one in its place. This is useful if you have a bad drive or want a second drive to travel into another region.

The dealer wants $800 to $1,400 for oem drives that are the same spinning hard disks as your original that will fail again one day. Also the ones I sell are not old used salvage hard disk drives.

A very common question is can I get a larger drive and put more than one region or DVD data on a disk. I'm sorry but the navigation unit can't be made to work that way so if you need to travel in multiple regions you need multiple drives. But I can discount them if you need multiple drives.

The replacement drive is guaranteed to work or I will replace it for as long as you own your car or until I cease selling drives.

This item is a replacement for Acura part numbers: 39010-SZ3-A820-M1 39010-SZ3-A830-M1 39010-SZ3-A831-M1 39010-SZ3-325RM 39010-S0K-A010-M2 39010-S0K-A030-M1 39100-SLK-A00-RM 39010-SZ3-315 39010-SZ3-325 39010-SZ3-335 39010-SZ3-A91 and any other part numbers for hard disks used over these years. The oldest ones have black cases with white or orange labels, then switched to silver cases with blue labels as in the picture above. Other label contents include Navigation Technologies Corp., PCMCIA Hard Disk Drive and CT521RM.

In the first two years hard disk updates and reloads were free. We were entitled to a reload if we changed to another region. After that Acura dealers tended to charge a fee to update it, typically $60-90. I paid my dealer to install all the regions of the most recent version on my set of drives. There are still a few that can do updates, do them correctly, some even do so for free now.

Most dealers have stopped doing hard disk updates once their specialized data loading PC stopped working. In some dealers that still have the equipment owners have reported the service department tries to setup their disk and ends up clobbering the data making it unusable until properly setup elsewhere.

In Dec 2002 Acura released the last disk-based software map updates and no new update is expected. Since then there is little or no support for our cars. Acura moved on to DVD based systems.

It is my belief that using standard computer industry procedures for handling software licenses applies to the navigation software. It should be legal to replace a failing drive with a copy of the same software you already own from a backup. The backup just replaces saved files with files you already had the license to use but temporarily lost access to when the prior drive failed.

The most recent version has seven regions. Note earlier versions were in different layouts.
