How do I increase the gain from my Aux Audio jack in the glove box (E60)?
I had an aux audio input jack installed in my E60 glove box many years ago, but even with my iphone audio turned all the way up, I can't hear most songs if my windows are down or if there is a lot of road noise, even with the volume knob turned all the way up.
1) Is there just a resistor I can change out that will increase the gain?
2) Looks like I need to remove the glove box to get to the wires...how do I do that?
Thanks for any help or other ideas.
