Looking to trade a JVC KD-G321 head unit for an nVidia graphic card. The card must be PCI, not PCIx. Must have at least 128MB. Head unit is in near mint condition, and works flawlessly. Will get pictures if needed. I WILL NOT ship first, so don't say I would have to. I will not add any amount of money, I want to do a straight across trade, unless I think the card isn't worth as much as the unit. I MAY accept an AGP card, but prefer PCI.
