Never know when you might need navigation. I would bet you can purchase a comparable X5 with navigation for the same price of one without. You may have to purchase the latest discs that come out annually to have updated maps. It is a little cumbersome entering an address but it works fine and is turn by turn loud and clear through the radio.

If you want to bring the nav more current, depending on the year of the X5, you can purchase the MX4 version for some other features. And if you want to add sat radio, bluetooth or connect your cell phone you can do that with a media bridge add on for far less than an aftermarket unit.
