Alright guys new to this,

Just wanting to know can I add an Extra Aux port to my bmw. I have one on the back of the centre console but wanting one in the glove box can anyone help me??

 

You can split the outputs using something like this. You'd have to snake the 2nd aux input through your interior.

 

Is that the only option for setting up, for having two 2 aux ? Was considering installing aux option to the front near the volume button, then also one in the rear by the rear passenger vents.

 

You can definitely have one installed in the front of the car. However, I'm not sure how expensive something like this would be.
The split AUX cord seems like a good idea if you're not trying to blow money to simply get an AUX port in the front of the car. You probably shouldn't go to the BMW dealership for this; I had to pay $80 for the proper AUX cord for my 08 535i. And thats just the cord - no installation or anything.
