Like new iPhone 3GS snap-in adaptor for cars with smartphone integration. I ordered this from Tischer a couple weeks ago, but now I'm changing phones. Works perfectly...used in my 2010 E92 M3, and it looks like it fits all E9X as long as you have smartphone integration.
This is OEM part # 84-21-2-158-683. Perfect condition, original box, and manuals.
I paid $184 plus shipping. Would like to sell for $140 (includes ground shipping to 48 states).
