Trying to hook up an external HDD with MP3 to the USB port - why cannot get the radio to recognize. Please help.

New guy - great to be here...thanks in advance.

I think the USB port is meant for MP3 players and MAYBE solidstate thumbdrives only.

External HDD that contain actual harddrives (with platters and the like) normally require an external power source along with a USB. Takes a lot of juice to make those things work.

So does that mean MY 550GB drive wont work but a little penstick jobby will? My Creative zen is not recognised by my car so will buy a small pen stick hard drive to load it with my tunes if you think it'll work?
Sometimes I wish I knew a bit more about computers!:lol:

It would work except for 2 problems: 1) the disk needs to be formatted as a FAT32 filesystem and 2) the USB port doesn't feed enough power to run the hard drive and read data at the same time. USB provides a +5V lead, but the amperage required by the hard drive is much greater than for the thumb/flash drive.

Oh and one more thing, car's personal data interface only indexes 2500 songs, which would all fit on the thumb drive anyway, so there's no point in using an external hard drive.

USB Radio and MP3 Functionality
The USB (Universal Serial Bus) will be a USB 2.0 port on the radio faceplate, on the IP or in the center console. This interface will give the customer the additional functionality of iPOD/MP3 command and control. Customers now have full radio control of the iPOD/MP3 audio files via the USB cable. A single USB connection allows digital audio transferring from the iPOD to the radio.The customer will also have playback capability with a USB memory stick (only MP3 and WMA files).

Note: Not all memory sticks are supported.

Customers have full radio control of the iPOD/MP3 audio files via the USB cable. A single USB connection allows digital audio transferring from the iPOD to the radio. The iPOD will be charging while connected to the radio.

Note: Video from the iPOD is NOT capable of being transferred to a Navigation radio display.

For the Chevrolet Cobalt, HHR and Malibu; Pontiac G5, G6, Solstice; and Saturn AURA, SKY, the USB port is on the faceplate of the radio. For all other models, it is located in the center console or IP.

For the Cadillac CTS only, a special iPOD cable (USB and AUX cable) is needed. This special cable comes delivered with the vehicle. In all cases, the iPOD will be charging while connected to the radio through the USB port when the vehicle is running or the RPA is active.

Problems with iPOD Not Connecting
If the infotainment system does not operate properly when using a device connected through the USB port, this may be due to an incompatible media device.

Important: DO NOT replace the radio or multimedia interface module due to a customer device incompatibility issue.

Verify the customer's media device is validated for this system using the list below. If the customer's device is a validated device for this system, follow the SI diagnostic procedure to isolate the fault. If the customer's device is not on the validated device list, explain to the customer that their particular unit is not compatible with the system.

Troubleshooting Tips for iPOD Devices
Check the version of the iPOD/MP3 to confirm that it is supported.
Unplug and Re-insert the iPOD to verify the customer complaint.
Verify the battery charge of the iPOD. A low battery condition on the iPOD may not allow it to connect to the radio. The iPOD may need to be charged before it can be controlled by the radio.
If the customer receives a "Device Not Supported" message on their radio or is having general iPOD/MP3 connection issues (and they have a supported device), they may need to reset their iPOD. To reset the iPOD:
• For the iPOD Nanos and Classic , Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again. Press and hold the Menu and Center (Select) buttons simultaneously until the Apple logo appears, about 6 to 8 seconds. You may need to repeat this step.

• For the iPOD Touch and iPhone: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider.

Have the customer check their cable for quality.
• Aftermarket cables can wear from use. The customer may need to purchase a new USB cable.

• Verify that cable extensions are not present. The extra capacitance may cause too large a signal drop for the iPOD to communicate with the radio.

If the customer receives a "Device Not Supported" message on their radio with an iPOD connected (and they have a supported device), the customer may need to download the latest firmware from the Apple website (Please visit www.apple.com for more information).

Important: These devices (and additional MP3 players) may be capable of connecting to the other USB options by internally setting the MP3 device to MSC (Mass Storage Class) mode. In this mode, the USB port will see the device as a flash drive. Please have the customer refer to their MP3 device manual on how to set the device to MSC. If the device is not able to be set to MSC, the customer must use the AUX jack.

Note: MTP mode must be used in order to transfer ANY Digital Rights Managment (DRM) protected content.
