I have the F700BT and have had this issue since I bought it. This is my only complaint about the unit. It does one of two things on a consistent basis. The iPod connection will either drop off when booting up or play only on the right or left channel from time to time. I have read over this forum and have found several people who have had this same problem and tried all of those fixes but they don't work. If they do work it seems to be a couple of days and then back to the same problem. This is what I have done so for to try and fix this problem, but it still is ongoing.
1.) I swapped the iPod cable from the Rocketfish AV cable to the Pioneer and problem still exist.
2.) I sent my the RCA/Power cable that plugs into the back of the unit to Pioneer in Ohio and had it tested by a tech who I talked with and he said there is nothing wrong it. He is blaming this problem on software, saying it needs to be reloaded and send in the unit (Which I will not do, unless catastrophic failure). When I asked him what software would be reloaded he said the 2.0 software and it will fix the problem.
Well now that the 3.0 has been released through this forum, I have to disagree with number 2 because it didn't work. When I loaded the 3.0 that was released on this site I did it 2 different ways. I basically did the upgrade option and the format and reload of the WINCE files through the service menu. The only thing that was fixed so far that I noticed, is the iPod is detected everytime on boot up. The audio fluctuating from channel to channel along with a "squeaking" noise (that is the only word I can use to describe it) is happening now.
So this brings me back to this forum to ask some more questions as to what could be the problem. Could it be that the WINCE files that came with my unit are bad and need replaced from someone on this forum who's CE files are good? I doubt it because upgrading to the 3.0 would have fixed this or it would have been a widely reported problem from others who have used the 3.0 on this site. To throw this out there as well I have upgraded to the 3.0.1 from pioneer and it didn't fix it either. I have never had this problem with my previous pioneer unit that used the same type of connection for the iPod.
Anyone have any thoughts, or had this same problem and what was done to fix it.
Thanks
Ryan
