This item came from a car with 78K documented miles. I bought the entire car for parts from a friend who had a frontal accident in January.
This is the latest gen MKIV DVD satellite navigation computer and works in many late model BMWs...comes with a map DVD inside (not sure which version). These sell refurbished for $850 WITHOUT map discs and on Ebay for over $800 - and that's if you don't have to buy from Europe or somewhere else.
Buy from a trusted board member with excellent sales feedback on many internet forums (I run two internet forums myself and also an online auto parts sales company - not BMW related - for 10 years now).
$700
