Presently the iPad's dock/USB connection is only for syncing to a computer and charging. It is not a general data/audio connection.
The car's USB port probably is not charing the iPad because it does not supply sufficient current to show that the iPad is charging when awake. The iPad supplied wall charger puts out 10 watts while most USB ports on computers put out only 1.2 amp.
My sister cannot use her iPad with either her Volvo S40 or her Pioneer VSX-1020-K, both of which work fine with my iPhone 3GS running iOS 4.
I understand that the iPad with its huge battery draws more current. It's OK if it doesn't charge. I do want it to work with the accessories.
Can anyone at Apple let us know if iOS 4 for the iPad will fix these issues?
Maybe there is a hardware difference? For some reason Apple says the camera connection kit (CCK) does not work for the 3G phone. From Apple's page for the CCK:
The Camera Connector features a USB interface. Just plug it into the dock connector port on your iPad, then attach your digital camera or iPhone using a USB cable (not included). iPhone 3G is not supported.
I'm a sofware developer on PCs. There are layers to the software to access devices on a USB bus. There is the basic transmit/receive. On top of that is the code to support various devices like keyboards and mass storage devices.
This applies at both ends.
It's quite possible that the iPhone 3G does not hold its end up properly.
When you connect a 3G to a computer, does it look like a camera? Can you access it as if it were a disk drive with a DCIM folder in the root?
Furthermore, the iPad doc has an analog audio out jack.
There is an accessory to deliver VGA video.
I really don't think it's a hardware issue.
