Hi i have a question about using my 40g in my truck i have a pioneer cd/mp3 player and i just recieved the Pioneer CD-RB10 IP-Bus to RCA Adapter CDRB10 that will allow me to connect my ipod to my cd player via rca cables. i was reading about this adapter when i bought and it siad the following.....

When connected to the IP-Bus connection of a Pioneer head unit, the device connected to the RCA ins must have an output voltage of 1 volt or less, or it must have a volume control so its output can be lowered. If the signal voltage is higher than 1 volt, the unit will distort and/or be damaged.

Ok i guess what i need to know is will i damage anything with my ipod? because if i turn the volume down on my ipod will i be ok. if so what volume setting on the ipod?

thanks
