My new (to me) 4.8is showed up today from California. Beautiful car, one owner, all paperwork, etc. It has a couple of interesting additions, one being a bluetooth kit for pairing to your phone. The other is a 30 pin iphone/ipod cable that is routed through the ash tray.

Problem is I can't figure out how to work it, spent an hour fiddling around with every option on the nav (with dsp) and still couldn't figure it out. On my e46 m3 the aux cable i added is easily accessible by going to aux mode. I can find no similar option on this vehicle. Am I missing something painfully obvious?

The CD changer also appears to be broken as there is a disc stuck which prevents the magazine from being used. Tried going into CD changer like i've seen in some of the youtube videos but doesn't seem to be working.

When my iPod is plugged into the cable it IS charging so it's clearly being recognized and it stops charging as soon as the ignition is turned off...

I've searched but been unable to find anything, I've attached a picture below. Can anyone identify the brand of this?
