I can only contribute this to the conversation.

No Bluetooth or HD but most of the other mod cons, and less than $200 at Amazon.

I had been toying around with getting a tube amp but will finally put in my NOS Pioneer sometime this winter.

 

Thinking about a new head unit with a flip out touch screen. Has anyone put one in the XF and any issues with the screen? Also would like a AUX adapter to plug the OBD into. Also any feedback on models and or brands would be great.
