That is the optional GPS mount. You can get the BMW Nav II or III and the BMW cradle which has some of the controls moved to the cradle, making them easier to use. You can not route auxiliaries through the GPS. Better (IMO) option is to purchase a Garmin motorcycle cradle and a Garmin GPS. The Garmin and BMW cradles are both by Garmin, the mounting holes match on both. If you use a 26xx, 27xx, or 28xx gps and the Garmin cradle, the unit will be more centered as the BMW cradle is offset for extra push buttons.
You can pull the stereo and access a port on the back for an auxiliary input. If you do a search on this site, you can find the part number for the cable you need and detailed instructions on how to install it. I have done this and would not do it again. I haven't found anything with sufficient output to drive the stereo without an auxiliary amp.
I use a 2730 which combines a XM radio, MP3 player, audio book player, and GPS into one unit. Run earbuds/helmet speakers direct, hook in into your com system, or use the built in FM transmitter play through the bike's stereo.
