Adding navigation to Alpine IVA-D300

[tipnitty]

I recently purchased this unit and would like to add the navigation. I know I need to buy the navigation unit to add to the brain but what else do i need to get up and running? any help would be much appreciated.

The nav unit, gps antenna, and all cabling, then the nav dvd. Cant imagine it would be more than that.. btw- which nav system are you going to buy?
