2010 GLK Dealer Installed Nav/Ipod/BlueTooth
a) What kind of system is this?
b) Will the Navigation CD update work on this? (My navigation has been stuck on "initializing" for the longest time
c) How do you "reboot" this system. All of a sudden, volume from iPod is not working (moved iPod to a different car and works). For the life of me, I can find a disconnect port or on/off button.
