Hey first post here!----Yes i searched first. I just bought a used 07 MCS with the Nav infotainment system. I have the factory aux input down by the cup holders. When i run a line to my phone or ipod the sound is horribly distorted like the signal is too strong. Now i read where you can adjust this line input (Aux Vol) on the regular stereos. Is there a way to do it on the Navigation head unit? If so help me out here! Love the car, hate the stereo so far.

 

Nothing huh? Bummer

 

When you select the aux output there is should be a volume setting there as well next to or around the aux option.

It's on my mini and on all my bmws from past and present. You can also try playing with the volume from your device as well.

 

ya....nope. just the tone, balance options.
