Thank you guys! I'll look up for the aux, I think I'll go with what TerminatorX5 suggested cause it seems like the best option for what I want. Or maybe I'll do the Dice Mediabridge so I can also use my steering wheel controls, haven't decided yet.

And thank you for the e30 comments, I've been thru a lot with this car. I've wanted to sell it on couple occasions but then I'll drive it and change my mind right away. Currently the brakes on the front are 316mm rotors from an e38 with custom aluminum hats and Brembo 4 piston calipers also from the 7 series, rears are 298mm from e39 with the stock e39 calipers. My plans are to go 345mm on the front with 4 piston Brembos from Evo8 and 325mm on the back with 2 piston Brembos for the Evo8 again. I know it might be an overkill but I can never get enough of big brakes
