iOs 4.1 sound quality issue using USB adapter

[sacharod]

Since the iOs 4.1 upgrade on my 3GS, the sound is not clean anymore in my Prius. We can now hear small scratches during the songs. I have tried with the 3GS of a friend same problem.

I don't have the GPS version of the Prius, only the JBL with iPod/iPhone USB kit. I guess the US equivalent is the Prius IV.

Does anybody experience the same issue?

Yes! i thought my speakers were blown, but then i started music playback through the CD and no crackle noise. It only happens when i play through my iPhone 4. And right after my iOS4.1 Update!!! WHAT THE FREAK IS GOING ON???

same here...static on my Itouch 64 after software update.

[spyderx]

huh, I better wait for my update then...

same prob w/ BT streaming?

[Thai]

Nope, BT audio streaming works great! No static...clear. In fact, i could not tell much difference b/w the USB (before static issue) and BT audio. So, i am now forced to use BT audio and using the USB only for charging. It will have to do for now until Apple fixes this.

[Colonel Ronson]

Yeah nobody seems to have any issues with BT. THe 4.1 update was supposed to fix the bluetooth issues, but F uped the USB playback. Others on other forums have reported similar issues with playback. ugh. i Might have to downgrade back to 4.02

I'm not experiencing any noise/scratchiness with my iPhone 4 and iOS 4.1 when hooked up via my iPod adaptor, though it isn't a Toyota-sourced adaptor. The bass is much better than going thru Bluetooth.

My LG Envy touch gives the scratchy/tinny sound when using bluetooth music streaming. However when another passenger uses their iphone bluetooth, the sound is perfect. I guess my phone distorts the output when in bluetooth mode. No probs. with usb/aux

[priuscritter]

I don't have the USB; I I use the aux Jack in the arm rest and connect that to the earphone Jack on the iPhone. Can anyone confirm if that has been affected by 4.1?

[Colonel Ronson]

I turned my phone to airplane mode and the static noise completely disappeared. i think somehow the 4.1 update might have affected the way the radios work and some people may get interference thru playback.
