Its been over a year since I had my F90BT installed and paired with my iphone. Lately, I have problems with my iPhone playing music correctly in the car. When plugged in with the pioneer cable, I first get a connection failed, please reconnect. Then when I plug it back it, my music will play but 95% of the music will go through the left speakers in the car and the right side gets the remaining 5%. This only happens when playing music through the iPhone. When playing it through the radio or CD, sounds will come out from all speakers. Is this a sign of my headunit dying or is there something wrong with my iphone? What can be the problem?

I'm having same problem with my iPod. I think it is a issue with the 3.0 software. I never had the issue before updating...

I had the same thing on my 900BT. It started after about two months. Came with 2.o factory update. Finally pulled unit and sent back under warranty. Came back with note that the software was reloaded. Works perfect. They did send a new cord also. Could have been bad cord but they did not say so.

I guess try and reload default software and start over.

Good Luck!

It has nothing to do with firmware/software. It is a hardware issue, one Pioneer is aware of. The plug that the white harness plugs into that connects all the RCA cables to the unit has a weak solder joint and causes the iPod RCA inputs from the iPod cable to short out either left or right or both, sometimes fade in and out (loosing connection). Send it in for repairs...

Does the whole unit have to be sent in or only the cable?

It's not the cable, it's the jack the cable plugs into on the back of the unit. The solder joints where the pins on that plug connect to the mainboard are loosing connection..

I've tried jiggling with the wires in the back and swapped the red/white around and swapped it back. It is currently working but if it stops, I'm going to send it in. Thanks for the help.

The lack of sound is coming back again and my warranty is about to expire in 2 weeks. Would changing to the Apple Composite cable help at all or am I better off sending in the unit before my warranty expires?
