My friend has a Sony Headunit. CDXM670, the ones with the black panel display face. He says it's 400 new, and it's about 6 months old. How much should it be worth? he wants 300, is that reasonable? and is pinky's mod compatible with this head unit?

 

Pinky's mod was the PAC SWI-3. The SWI-3 is no longer made, its now the universial SWI-X (does the exact same thing). Anywho, the CDXM670 will NOT work with the SWI-X and it is specifically listed on www.go2pac.net as such. It's pointless to install a deck without the possiblity of having dash controls. PLUS you can get a better deck for less money.

 

thanks lucid
