Part of the partout. There are:

2005-2007 Coupe/ 2005-2006 Sedan OEM radio trim plates and radio/climate controls. They were functional when removed, but that was about a decade ago, so I'm listing as non-functional cosmetic components only. $15 + shipping each
OEM climate controls rigged to a metra climate control board. It was put together for a Vaydor conversion many years ago and never tested, as it was going to be going in a 2003/2004 and not compatible with my 2005, and the owner never finished the conversion. Also sold as a cosmetic component only. $10 + shipping.
SiriusXM receiver box, wiring, antenna. Untested, removed from junkyard G35. $10 + shipping.
Factory nav screen only. Working when removed to install aftermarket radio in that spot. $5 + shipping.
2005-2007 Coupe/ 2005-2006 Sedan OEM under-clock trim. Useful if you damage yours when putting in a radio.
