Sandisk u3 cruzer micro usb device stopped playing when put in car stereo. It was playing fine but now nothing my car stereo say's it's reading the device but thats it

According to Scandisk:

As of October 1st 2009, SanDisk started shipping the Cruzer Micro (SDCZ6-XXX) product line without the U3 software pre-installed on the device.

During the transition period, there may have been a small number of devices that were packaged in older packaging that states the device includes the U3 software. If you purchased one of these devices and would like to use the U3 software, please download and install it.

If this is the U3 SanDisk Cruzer....U3 drives present themselves as two devices. One of them appears as a read-only CD drive that contains all the **** programs and the other is the writeable USB stick part. It comes with two partitions on it, one for data, and the other called "U3 Partition" which is read-only.

U3 is the software application launcher, download and replace it with an updated version. This being availibile on www.sandisk.com site. Hope it helps

My dear! first install software only without attaching USB when your USB required the software or driver then attach it or if your software does not required USB attach during installation, you have to attach it after the installing software. May it require reboot your system. Now your USB sandisk u3 cruzer micro device will work.
thank you

1. Download this tool:

2. Format

(WARNING: After running this low level format tool,
the whole USB flash disk surface will be fully erased.
Therefore, data restoration will be impossible after using this utility!)

We can fix it -- and recover the data (provided it is recoverable -- which it generally is). If we don't get your data back, we ship the drive back to you and you pay nothing. We've been recovering data for over 16 years and are successful about 85% of the time.

Hi,
Is your Sandisk Micro USB enabled with password on U3 (a program to install programs on the go, for more information go to www.u3.com)? If it is, go to a Windows machine and disable the password. Then format your drive.
hope this helps!

Strange... Vista does seem to have a problem with everything Sandisk...

Anyway, this should be all you need:

Launchpad Installer

Launchpad Uninstaller

Your SanDisk Cruzer® Micro SDCZ6-2048 (2 GB) USB 2.0" may be giving problem due to the internal errors.
Therefore 2 GB card may be scaned through anti virus, if problem repeats then format ur card from the computer.

Is the account that your tying to access the drive with an Administrator account? If not, Log in as Administrator and try to access the new drive. If you ARE using Administrator privileges on the vista machine, the problem lies in the U3 smart driver. Try downloading and installing the drivers for the XP SP2 os on scan disks website, If vista rejects the install package off of the scan disk website, let me know and i'll extract the drivers and build an install for them for you.
