DVD Navigation or no DVD Navigation?

I am about to buy an X3 with Premium Package, Bi-Xenons, SIRIUS, and that is basically it (auto of course) and I was wondering if it would be worth it to buy the DVD Navigation?

And also, does anybody know if BMW is going to raise the price of the '07 when they come out due to the HP increase?

Thanks.

Hello, George Bitar here,

I think the DVD navigation system is well worth it.
Thanks,
