I am looking at upgrading my stock Business Cd Player from a 2001 BMW Z3. This is made by Blaupunkt. This unit also allows you to use your factory 6-disc CD changer and is compatible with steering wheel controls (BMW i-bus). Unit works flawless and will come with the manual and key code ( Idon't have the key card but just got the correct code from dealer last week after replacing the battery, so I know it works) There are no dead pixels. I won't know for about a week If Iwill sell it, but just wanna see how many are interested. I am looking for 500.00, and can provide pics and additional info if needed. Please PM me if interested.
