With the Release of iOS 4.2.1; I rushed to update hoping that it would fix my USB to Car Audio, but it doesnt, what exactly is Apple trying to accomplish by removing functionality..

I own an Eclipse AVN726E which I've come to learn is also the system that Toyota/Lexus uses in some of their vehicles..

Granted I can play audio through the Bluetooth Audio selection but then the devices doesnt charge..

I plug in my iPhone 4 and it just hangs on "Reading..."

Does anyone have any ideas or anything that I can try to make this work..
Or is this all in the hands of Apple..

    Our Kenwood unit was doing the "Reading..." hang. Googleing the problem, we found that resetting the unit (pressing a small button with a paper clip) cleared the problem. Just a thought...

    It's not Apples responsibility at all.
    They did not make the stereo.

    Ask whoever madecthe stereo how or when they will fix their product to be iOS 4.2 compatible.

    I've got a Kenwood KDC-MP345U and had the "Reading" hang problem after doing the 4.2.1 update. This worked for me...

    I simply did a full restore using the Restore button in iTunes. It will ask you if you want to back up your phone first -- cancel out and do it! Then hit the Restore button again. This will restore the iPhone to factory settings. The phone then will update itself to the latest operating system (4.2.1). Finally, restore your own settings from your last backup. When I plugged in the phone into the MP3U, I got the "Reading" message for about 2 seconds and then everything went back to normal. Also, all my settings on the phone are exactly as before -- don't skip the backup immediately before the Restore.

    Hope this helps someone else...

    Who is this fool Johnathan Burger? The interface between our Stereos and Iphones was working well in ios 4.0.1, and the genius Apple software team has managed to remove this functionality, and some halfwit suggests that we ask the stereo manufacturers to fix this? Has Apple done this in an attempt to extract more licence fees, or are they just incompetent?

    When you have a ton of car manufacturers with this problem after 4.1 (when everything worked fine before) then Apple change something to cause the problem. Apple needs to address it.

    As I posted in the other Volvo car dock thread, 4.1 broke Nissan dock compatibility, and 4.2.1 restored it. They changed something, and changed something else, and now a different subset of car audio docks do and don't work.

    J. Berger= Apple Fanboy. If the car stereo worked with every OS update in the last 3 years (like mine did), and it suddenly won't recognize the iPhone, my money says Apple changed/screwed something up. But I digress- I reset my stereo (remove the faceplate and find the reset button) and.... It worked. That is the first time I have had to do that in order to get the USB input to work.

    I have a Volvo with USB connection and I have never had problems playing the iPod or other audio applications through the car's system... until now. When I connect the iPhone to the car, the car stereo displays "loading iPod", then it says, "Unreadable."

    I think there is no question that this is on Apple, because one the the enhancements that Apple lists in in the description of 4.2 is "Improves audio playback to car stereos via USB."

    So far, my improvement is that the feature went from working perfectly, to not working at all. I drive a lot for my business and listen to Podcasts and music through my iPhone. I cannot believe that Apple could let something like this slide through.

    I have tried all the suggestions - still cant get any connection going. The really annoying thing is that the customer contempt centre thinks this is funny and will not allow us to regress to 4.0.1, even though this would solve the problem.

    I have a Pioneer DEH-P5200HD head unit. This is less than a year old. It worked fine with iOS 3.X, but since 4.0 is released it has problems connecting to my iPhone 3G. 4.2 improved the situation some, but it's still very flaky. Often I have to reboot the iPhone before it will connect and start playing. Other times I have to plug and unplug multiple times before it finally syncs and starts working. Rarely does it work correctly on the first try. It seems to me that when the phone is under any kind of load it does not respond to the head unit fast enough, which causes everything to get messed up. Apple needs to somehow dedicate processing to this functionality to fix this problem, in my opinion.
