    Sorry to add a "me too" post without anything really constructive to say...

    I have the exact same problem. I have a Pioneer DEH-P7000BT stereo. I originally had an iPhone 3G which I used both for Bluetooth audio streaming and hands-free. Everything worked fine until I upgraded to my current iPhone 3GS. Now, Bluetooth audio streaming still works fine, but I have the same garbled/interference when using the phone for hands free-phone calls.

    I took my phone into the local Apple Store, and the Genius that I worked with was unable to reproduce the problem with a Bluetooth headset in-store. However, he did swap my phone out for a new one. Unfortunately this didn't help.

    This has become a bigger issue since January 1, when a local hands-free law went into effect.

    I will also send feedback to Apple and hope for a fix in the next firmware release.

    Thanks! Will do. Heartening to see I'm not alone.

    I wouldn't worry about it, ANY use of a mobile phone in a car will soon be banned anyway.

    "States should ban drivers from using hand-held _and hands-free_ cell phones, and businesses should prohibit employees from using cell phones while driving on the job, the congressionally chartered National Safety Council says,"

    Another Pioneer Head unit owner here with unusable bluetooth. I know for a fact the issue started after the upgrade to 3.1.2 on my iPhone 3GS.

    Unfortunately, it's impossible to legitimately downgrade to 3.01 to resolve this issue for further testing. Not sure what to do, I spent a lot of money on my head unit and use it extensively so this is a big issue for me.

    Had a genius appointment today - more of a precauation since I knew there wasn't going to be much they could do. They did not seem to be aware of a specific issue with Pioneer or Alpine units, but some general bluetooth issues with 3.1.2. (KOP, PA Store, btw).

    I don't see a resolution for this issue coming any time soon. Personally, I'm trying to locate a 32G 3GS to replace my phone with since I cannot backrev the firmware.

    Hello,

    I have a DEH-P8080BT car stereo and a iPhone 3GS 32GB and I am having the same problem. On every call, after 15-30 seconds I start to get garble interference from time to time on both ends. If I use bluetooth to stream music to the stereo, theres no interference, so the problem is only when I am using the phone.

    I used to connect an iPhone 3G 16GB on this same stereo and everything worked fine. After I bought the 3GS, the problems started.

    I hope we can find a solution soon.

    I have the same problem with the FH800BT Premier unit and an iPhone 3GS running 3.1.2.

    At least there's some comfort in knowing that I'm not alone in experiencing this frustrating problem. Resets, changing the speaker balance, Echo Cancellation all had no effect for me. Very annoying.

    Back to the earbud I guess until the 3.2 comes out.

    Have you tried turning WiFi off on your iPhone? I use to have this issues between my iPhone and the Bose system in my Mazda. Shutting down WiFi cleared it up and as long as WiFi is down, I dont have any issues at all.

    I emailed pioneer tech support about this issue. Specifically asking:

    "Can you confirm the pioneer DEH-P7000BT is compatible with the Iphone 3GS running iphone firmware 3.1.2?"

    ...and this is the response I got:

    "Thank you for contacting Pioneer Electronics, Inc.
    It is compatible, but we cannot guarantee that the interface between the I-Phone and the radio will be 100%."

    Whatever that means.. :-/ I would encourage everyone who is having issues with this to email Apple and Pioneer:

    Just wanted to add on to this thread to say that I am experiencing the exact same problem with my iPhone 3GS 16GB 3.1.2

    I have garbled sound when making calls using Bluetooth with my Pioneer DEH-P700BT car stereo. My old Nokia E51 was flawless and to think that I might have to get a new stereo to solve this is really frustrating.

    This issue along with being unable to achieve a full day without having to recharge makes me wonder if I have made a huge mistake tying myself to a 24 month contract with an iPhone.

    Does anybody know when the next iPhone firmware is coming out?
    Is there a way to revert to an older iPhone firmware which does not have this issue? 3.0 maybe?
    I really hope either Pioneer or Apple will take some steps to resolve this!

    My Follow-up. Tried the following to address this issue with NO LUCK:

    -Disabled Wi-fi
    -Disabled 3G (Edge only)
    -Tried switching sources (to earbuds) then back during calls.
    -Actually was able to downgrade to 3.1.0
    -Tried offering a one-for-one swap with someone plus $100 if they had a 3.0.1 iPhone
    -Tried buying a 3.0.1 outright - can't find any!

    None of the above worked. As determined as I am to fix this issue, the fact remains it was introduced at the 3.1.1 firmware (which was quickly replaced by 3.1.2 due to battery drain issues).

    This needs to be addressed by Apple. I've been to the store, I've called Apple Support. I don't know how to get someone to pay some attention to this problem.

    - I saw discussion of the new dev for 3.2, but don't didn't get any indication of release.

    Is there a way to revert to an older iPhone firmware which does not have this issue? 3.0 maybe?
    - There is none. Perhaps if you can find someone willing to trade with you.

    I really hope either Pioneer or Apple will take some steps to resolve this!
    - I agree. I don't think Pioneer will do anything about it, however, since I haven't found any evidence of other phones having the issue. Also, it's pretty clear that the issue was introduced with 3.1.1 or 3.1.2. I know the two iPhones in my household worked flawlessly with my P8000BT when they were at 3.0.1.

    Anyone test this out with the newly released iPhone 3.1.3 software? I really want to purchase this stereo, but I'm hesitating because of reading about this issue.

    I will test 3.1.3, but not until tomorrow. I'll try to post back here asap with my results.

    Hi Guys

    Just updated to 3.1.3 and tested in my car with no improvement
    Sound is still garbled. The cycles between distortion and clarity seemed to be slightly longer however.

    I wonder if Pioneer could fix this? I am thinking of ditching my Pioneer DEH-P700BT for something else. Any suggestions on what to get?
