I noticed on my iPod that the audio volume is much lower than the RADIO volume... Does this Seidio mount makes it worst? Would it be less volume? Also, do you get any noises when charge and play music at the same time? (i'm getting lots of noise when use with Belkin Car Charger).spockcat said:Line out. You canno adjust the volume. The power output is equivilant to about 80% of the maximum output of the iPod.
