I purchased this unit from J & T Distributing in April of this year. I installed it and used it for maybe a week. It works great and fits perfectly in the E46, but I wanted Apple CarPlay and decided to upgrade to a new Pioneer 8201 NEX instead of buying the CarPlay kit from Dynavin.
It comes with everything except the microphone and the GPS antenna. You can both on Amazon for under 20 bucks. I shortened and spliced the power jack cord on the back of the unit for a better fit.
I paid $650 for it and it's still under the factory warranty. I'm asking $450 + whatever shipping costs may be incurred.
Thanks!
