iOS 4.2 Still NO Fix for USB Car Audio (AVN726E)

Shane, I had this problem when I first got my iPhone 4. My iPod Nano worked flawlessly with my stereo, but when using my iPhone 4, it would just constantly hang at "Checking" (what I assume to be the equivalent to your "Reading...").

I was able to get around this by sort of jump starting my iPhone. I'd disconnect my iPhone, go to the iPod app, start the music by either hitting shuffle or a specfic playlist, and while playing then attach it to my stereo. It's still a little buggy, but it works 80% of the time.

Hope this helps.

Same problems using USB interface with iPhone 4 OS4.1 and a 2010 Toyota Tundra non-JBL audio system
Error 5 message has gotten worse until now it will never read the iPhone4's iPod function

Very frustrating !
Sure would like a REAL fix so it works all the time without any problems

Not to throw more fuel on the fire here, I honestly believe its actually Eclipses responsibly. They write the firmware to be compatible for the components that plug into the Head Unit. And, since they are now out the aftermarket industry... chances are its not that important to them to update with new iOS in mind? Shame really - I enjoyed many good functions prior to this update.
I always have bluetooth - just noe song titles.

My fingers are crossed they'll support it as time goes on- it was an extremely popular HN when it was released and still kicks ***. But yes, it takes a bit more finagling now.

UPDATE!

There is fix for this HN -

Try this for proof Apple messed up the latest update for Ipod Touch anyways;

I'm no tech head but it looked pretty obvious to me;
1. I just purchased a new Toyota Corolla 2011 with a USB port for Ipod.
2. My wife and I happen to own 2 Gen3 Ipod touch
3. My Ipod has the latest version of firmware 4.2.1 (8C148)
4. The other Ipod has firmware 3.1.2 (7D11)- I never kept this one updated

I try to connect my Ipod with the latest firmware to the car - No success, I get this message "Load" nothing else

I try the Ipod with the old version 3.1.2 (7D11)- No problem what so ever, connection straight away.

Conclusion - Stay well away from the updating, and where can we get the old version.

Since 4.2.1 update, the AVN726E in my Nissan X-trail also hangs on 'Reading...' when connecting iPhone 3G via USB. A suggested fix is to press AVN726E RESET BUTTON but this only deletes AVN726E phone book which are a major pain to upload. If Eclipse/AVN726E claims Apple compatibility, perhaps they should be providing a firmware update to suit iOS4 although Apple seems to be at fault as it was working & now doesn't.
I will be contacting Eclipse / Fujitsu to see if there is an update; either way, a fix is needed!
