| Hello, I wanted to know if I could use the OEM BMW Business CD Radio head unit in my 1990 BMW 535i? It's from Germany and is in great condition. Made in 1996. But the seller says it works in all BMW, E12, E28, E34, E36, E30, E34 incl. M3 and M5 and Z3. etc. It has a CD player, RDS, AM/FM Radio and the part number is 6512 - 8 352 865. Could anyone with some knowlege or reference verify if it works on the BMW E34 (1990 BMW 535iA)? I attached a photo of the unit itself showing all the part number, name, etc, so please let me know what you think about it's compatibility with the E34. |
