I purchased a Blaupunkt from another member some months back.
Liked the idea that it was to be a simple plug and play.
It wasn't.
I was replacing the orginal unit that had a cd and gps in it.
I had to buy an antenna adapt and a plug adapt.
Works fine
The Blaupunkt had been used by previous member in his Crossfire and had been plug and play.
Can not explain why I had to buy adapts but did.
