cntrylvr79 Posted May 1, 2007 Report Share Posted May 1, 2007 Can you snap a pic of the stock radio? Cause I don't remeber what the thing looks like. From that I could tell ya what you'd need. Quote Link to post Share on other sites
Nero534 Posted May 1, 2007 Author Report Share Posted May 1, 2007 Well the local shop here got me a GMOS-LAN-02 interface that was not even close for my envoy. I called metra this morning and they state i need a GMOS-04 interface. SO I am going to try that one i guess. i see CC sells them also...I appericate your responce and will be back for sure if this one dont work, man the D3 looks so clean sitting in there with the wood grain trim.

cntrylvr79 Posted May 1, 2007 Report Share Posted May 1, 2007 Ok the os04 will work. If you can get the newer version of it, it'll have the vss and everything there for you. Quote Link to post Share on other sites
