I have been searching many forums trying to see if anyone else is having this problem with their 930bt. The issue that I am having is that the sound I get from connecting my iphone via the pioneer 51 cable is not as good as when I connect my iphone via bluetooth. It sounds much better when connected with bluetooth. Has anyone else noticed this and is there a remedy? Thanks to all that respond.

I think I have (sorta) the same problem when using my 3GS (although I haven't tried it with my 4S yet). I notice a definite loss in volume & fidelity when listening to a track through the iPhone hooked up to the pioneer cable versus listening to the same track streaming through BT (or even off of an SD card). One would think ths could be fixed using the SLA function on the x930bt to adjust the input level of the iPod, but even with that, it still doesn't sound quite right...

I have this same problem. My Iphone 4s when connected to cable only plays on one side of my car, which is unusual. I tried a different ipod and still not working right. Think the cables broken or what ? When played through BT or radio it sounds great.
