Car stereo doesn't recognize USB after updrage to iOS 4

After the upgrade, I plugged device into USB port on stereo and it now says read error on the head unit. Kenwood has no official help as of today other than to say they only support up to 3gs, no reference to OS version. Model number is KDC-X693. Anyone else run into this or have suggestions?

Windows 7

Correction, the display on the head unit says, "iPod Error."

I'll drop back to version 3 before I let a nice unit that's not even 6 months old be rendered unusable. Kenwood might be able to fix this with a firmware update (still not sure how to on this unit), but this has to be something Apple did in it's update, since it worked perfectly fine before. I'm finding similar issues with various manufacturers when researching.

Some of the Alpine head units don't work either. Mine is getting an error as well.

On my pioneer unit i could get my 3GS to connect but every time i skipped songs it would disconnect and then reconnect, it was very annoying. All i did was do a hard reset holding the power and home buttons and after it restarted it worked fine. This worked for me not sure it will work for you.

I assume when you did the hard reset it took you back to version 3?

What does a hard reset actually do? Does it delete your settings?

I'm not 100% sure exactly what it does but you wont lose any settings.

I could have sworn I did this already, but cycling power to the device again seemed to fix it for me. You might try turning the iphone off and back on again before trying a hard reset. I thought a hard reset restored everything to factory settings.

Powering off and back on AFTER the update was completed fixed this for me.

Just because it said "Made for ipod" doesnt mean that if apple do a major change (like what iOS4 is) that its going to instantly be supported !
We arent even 24hrs past the release of the firmware!
It may take some time for firmware updates for Alpine \ Kenwood units to roll through! Im yet to check and see if it works on my DDX812 (kenwood)

It took powering mine off and back on twice to get it to work. Give that a try.

Yeah, you know what? It should.

Apple knows very well that almost everyone on the planet has an iPod/iPhone and most likely some peripheral to go along with it and that they have some "lifelong" customers. There are some "legacy" things that haven't changed yet (connection port anyone?) and shouldn't ever change if they are going to keep updating the line. Kinda reminds me when many many accessories were deemed obsolete when they discontinued firewire support on the i line...until the Schoshe Passport came out, anyway.
