iPhone 4.1 - Car Audio doesn't work anymore...

I update my iphone 3GS to 4.1. It now won't play through my Eclipse (Subaru) car sound system. It did before! This is clearly an Apple issue, how do I fix this?

iPhone 3GS, iOS 4

Joint the club..I have a 2010 Series 200 Land Cruiser and since updating to 4.1 I am no longer able to connect my iphone to the stereo using the USB cable (worked fine with 4.0)!!!!!. It just sits on the load screen for ages and ages (over 30 minutes). Bluetooth works fine but the phone will not charge through bluetooth!!!!

Well done Apple.....your quality control is **** poor!!!

Will share my experience .... a little different but not satisfactory with 4.1. Phone has been upgraded from iOS3 to 4.0 to 4.02 and has worked fine on a Lexus IS250 2010 model. Upgraded to 4.1 and reset before using. Worked initially and then could not read etc as reported here. Eventually did a full restore of firmware 4.1 in iTunes and it worked. Sort of. Scrolling issue remains but I can live with that. However, sound seemed to break up for microseconds at a time ... almost like inteference in the car. It was usable but annoying.
I found that Apple have not yet deactivated v4.02 and have downgraded. Everything is back to "normal" especially sound, so I am staying there for now. " If it ain't broke, don't fix it"!

I'm in the same boat with my iPhone 3GS. I have a 2010 Camaro SS, which has a USB port in the glovebox. I plug my iPhone in, and it gives me a message "Device is not optimized, blah blah blah", but it would allow me to stream music to the car. The trouble I have is that from time to time, the car won't recognize the device, or will simply not play. Or when I get it to start playing, it cuts in and out with static. I tried pairing it with bluetooth, and it would cut in and out with empty sound, in the same fashion. I did a restore on my iPhone and now it has trouble pairing. To top it off, when I was trying to call my parents, the phone would cut in and out, and even dropped the calls. I'm confident this all stems from upgrading to IOS 4.0 and up, since I had no troubles prior.

Same for me on my Prius 2010 through Cable adapter! The sound is not clean anymore like listening to an old LP !

I thought Apple loved music. Looks like they couldn't care less... The worse is that you cannot downgrade!

The best IOS for me was 3.2.1. It was fast and I had no issues with my iPhone in the car using an Alpine IVA-W505 with the iPOD Full Speed connection to the head unit. I've had no issues with the iPhone and the Alpine head unit inside the car from a sound quality standpoint until the IOS 4.1. This was fine with IOS 4.0.2.

Please try to figure out what happened between the 2 IOS versions. I'd even beta test it for you it you want to because it seems like it wasn't thoroughly tested.
