Using an iPod Touch/iOS 4 with a Pioneer FH-P800BT

I am having the same issue. I have to begin playing the track from my ipod then connect. It is giving me a Error 11 message on the head unit screen. Any ideas?

I figure it out. Go to the settings app, then the General tab, and at the bottom click the RESET ALL SETTINGS. It won't delete anything. That is how I got mine to work. I can see and change all songs, etc. now.

I have an alpine ida-x200 and I have also had issues with the iOS 4 upgrade. The performance of the stereo controls are extremely slow by comparison to the previous versions. I've been using the usb connection, but yesterday I ran out to by the high-speed cable that alpine offers. The performance between the two is just about the same - albeit the high-speed cable is a tinge faster. Scrolling via the deck unit's wheel is so slow that it's basically unusable.


I did see that "no songs" issue once as well. I just disconnected the ipod and plugged it in again and it worked. One time the player was "playing" and I had no audio.

I needed to get the word out there. I hope apple sees these. I'm definitely going to have to revert to the previous OS version until something can be done about this.

Same issue. My 3GS worked fine with my FH-P800BT stereo until I updated to OS4. I could not connect to the BT audio to play music, but the phone still worked. I cleared settings to try to reconnect, and now I can not get the phone or stereo to work. Was flawless before OS4. A real disappointment now.

I am also having the following problems with my Kenwood stereo immediately after updating to IOS 4.

1. Link Search no longer functions.
2. It takes a long time for artist names to appear when scrolling through artists under the list command, which pretty much makes looking for a specific song a nightmare. Sometimes the artist or song title won't display at all...it will just remain blank on the LCD.

I have a CDA-117 and see some similar issues as you polairecks. I
found out that it occurs any time that I add music or anything that may
change the library and playlists. What I do is any time I add music
or playlists, I do a hard reset on the Ipod (hold home and sleep buttons
until screen goes black and reboots) while not connected to the deck.
When I plug it into my deck, it then performs as before. It seems on my
CDA-117, it downloads the library and playlists and saves them, but doesn't
see any changes in the Ipod and gets confused. A reset of the Ipod apparently
flags the deck that the Ipod was reset and the deck then downloads the new data.
Try it, may work for you.

Others may want to try it as well. Using this method, nothing will be changed
changed in the Ipod since it is simply rebooting as opposed to the Reset settings method.

I have very similar issues with my Alpine IVA-W200. I thought it may be Alpine specific, but after reading this thread it is definitely iOS 4 specific. This really irritates me. First the shenanigans with the FireWire/USB power switch, now totally hosing compatibility with old Apple Partner devices.

I have an AVH-P3100DVD that was rendered useless along with my i-pod touch when they did the update to 4.1 What the heck am I supposed to do now? Not listen to music until they decide to fix it with a patch? I will never trust an "upgrade" of the OS again.

I have an iPhone 3GS, upgraded to iOS4.1 and now my Alpine iDA X200 has static crackles on playback every few seconds, terrible quality. This doesn't happen with an older iPod classic 80gig.

Before upgrade, had problems where headunit work occasionally continuerestart a song every 10 sec after you had pressed the back button. Also had some silent drop outs (still annoying, but far less annoying), and menu dysfunction on the headunit not displaying text properly, or playlists. Also had it being connected, saying it was playing, but being silent.

Anyone found a solution? Apple - do we have new unwelcome surprises to look forward to each OS upgrade. Can't stand to use my head deck!

Just another "me, too". I have a Pioneer AVH-P4100DVD. Since the iOS 4 upgrade, it now cuts out often, sometimes spending more time cut out than actually playing audio. It's rendered my iPod Touch unusable. No problems ever in the past six months until this upgrade.

I hope Apple fixes this quickly, because my car stereo is now useless.
