Yes, have xenon lights, rear seat heaters..... Pretty much everything that I can think of less PDC and Nav.

Anything for Tire monitoring?

In your opinion, would it be less expensive to buy the nav harness from bimmernav and source the rest of the parts or just spend the 2800 on the complete kit that they offer? Is there modules to allow me to install atleast one camera, as well as other inputs, ie dvd to be shown on the monitor? I would assume that Dice will work the same.
