Congratulations and welcome to the X Outpost, Please let us know if it's 3.0,4.4 or 4.8is and what options only then one can tell if it's a good deal or not.

Am sure some memebers will chime on the aftermarket Nav unit, I have a old tom tom in my beater and OEM nav on my X, i like the look of the OEM nav and has enough options for me to not want to change it, however am new to the X as well and am finding my way around it, seems to have a lot of hidden features (This car) and the members here have helped me unlock some of them.
