iPhone 3GS and Pioneer car deck not playing nice.

Yeah, especially since 3.0.1 was supposed to just be a security fix for the SMS exploit.

Then again, I didn't get one audio glitch on my 30 minute drive to work this morning. Same drive yesterday, I had to reconnect it twice...

I have the same problem. It's either a non compatibility issue with the Pioneer USB not understanding 3.0 and above software, or the iPhone 3.0 software is not liking the Pioneer USB. On my 3g it worked just fine, when i updated to 3.0 it started the problems. I get error-19 on the pioneer deck many times, and the phone doesn't charge half the time, and every once and a while, the phone decides it wants to completely reboot! now that is really annoying! but luckily i have wired in my ipod into the glove box incase something goes wrong with the iphone. it just ***** that it wont work, i like to keep my phone charged as much as possible. I would expect more that it is a problem with the pioneer than the phone personally... My phone might say that it is not supported with several devices and ask if i would like to turn signal off, but it still does what it is supposed to if you leave signal on. it charges, plays audio, and works just as if it was supported... the fact that the pioneer says error-19 to me all the time and i have to unplug and replug says that pioneer isnt recognizing the device... but what can be done? I have called pioneer about the problem and they say they dont know what to tell me.. so its really about when is pioneer going to update their decks to work with 3.0 software and above, and they better believe they will be getting me a new deck that works as soon as that happens! if anyone else has talked to pioneer about it and got any different answers please post them!

I have a kenwood stereo in my car with a usb hookup. 3.01 updated and now it causes all kinds of problems. I can no longer use the controls on my iphone 3gs while in ipod mode and hooked to the stereo. Also, it randomly shuts down, and also causes my stereo to freak out and do strange things. Pretty annoying and pretty poor performance from Apple. Im going to go back to the 3.0 and see what happens. I also find it absurd that some chargers and docks will not work with the 3gs. Not very convienent for loyal apple iphone and ipod users.

I've the sam issue with my pioneer DEH-P3100UB. I first thougt it's because of my DIY installation of the head unit, but then I read this discussion. My temporary solution is to press the source button three times to switch via aux and tuner back to the usb source, and then it works agan for a while...

I have the same problem with my 3G phone running firmware 3.0.1
When I got the phone I plugged it into my head unit Clarion DB285USB
Everything worked great for a week long road trip to Colorado.
Over 40 hours of use in the car and not a single issue.
I got a refurbished 8Gig 3G... I am not sure of what firmware came on it.
After I upgraded the firmware to 3.0.1 the phone will charge when plugged into the headunit but will not play.
I also bought a $70 Ipod ready Phillips speaker system and it does the same thing.
The iPhone displays the "This accessory is not designed for iphone" message and will not play.
The Iphone always displayed this message but always played.
Since 3.0.1 it will not play.
Any ideas???

I was going to buy the Pioneer DEH-P3100UB for my 3GS. Can you guys confirm if the firmware 3.1 fixed this issue?

no, 3.1 did not fix the issue.. pretty sure it is a pioneer issue and they will have to set up a firmware update, and who knows how long that could take..

So... I've just opened a support ticket in Pioneer's site. I suggest you all do the same:

Thanks,

Everyone, I have the Pioneer AVIC 900BT and an ipone 3GS. I also have an iPod touch 2nd gen both with 3.1 software. I am having the same issue that everyone else here is reporting. Prior to getting the 3Gs I had the 3G. Charging was not an issue at all. Got my 3Gs around the same time 3.0 came out so I thought it was either a 3Gs issue or 3.0. Now, my iphone charges while connected to my Pioneer every blue moon; more not charging than charging. I even purchased the Pioneer software upgrade (v.3.0) hoping that would solve the issue. No luck. I upgraded to 3.1 thinking that would help. No luck. I just plugged my iPod touch into the Pioneer...charged right away. My conclusion is that it's a 3Gs issue. I guess I'll give Pioneer a call and see what they say.

As far as I can tell, 3.1 fixed the occasional "NO SONGS", "ERROR-19" or (much more frequent) audio glitches with my Pioneer DEH-5100UB

yea, i have not had the error-19 or any audio glitches since the 3.1 update, tho i have not been in the car too much since updating on wed... still has the charging issue without a doubt tho.

if you have Bluetooth with your decks (my premier deck does but doesnt work with iphone just ipod)
pair your phone to your deck and go get a third party car charger my griffin charger works fine on my 3G from firmware 2 up to now 3.1 and actually 3.1 improved the BT audio streaming (3.0 occasionally has a few drops in the tunes which was quite irritating)

Here is what Pioneer says:

"Thank you for contacting Pioneer Electronics, Inc.
There are no updates for the Pioneer radio.
You would need to check with Apple, see if they have an update to correct what their update altered."

Sorry, but the 3.1 update to the 3GS did not improve BT audio performance. My Pioneer 5100 deck is dropping more than ever and now I'm having issues using the external mic when bluetoothing on the phone. Wishing I never went to 3.1...

I found that my premier deck plays without drops now that I updated to 3.1

battery is much better too with 3.0 under heavy use batter would last an hour maybe two

now it goes all day medium to heavy use
