I have a used GMOS-LAN-04 for sale. Works perfect. I had it in my cobalt but my brother bought my headunit from me so im going back to the ole stocker. Everything on it is perfect but one thing. The little insert that holds down the 14 pin connector i lost. Still works flawlessly though. This is for 06-Up Cobalts with onstar and the pioneer audio i do believe. Asking $70 Shipped and ill through in a single din dash mount thing for a headunit.

 

do u still have this?
