Hey everybody out there I have a question I recently installed my avic-x940bt in my denali and I want to get a cd changer what I need to know is the the cdx-p680 compatible with this unit.....

Has anyone seen an antenna adaptor so that I can use my factory navigation antenna to connect to my avic x940bt....

And that worked for you I thought the plug for the avic radio was round not square but I will check it out....

Is there an adapter to connect the gm gps antenna to avic x940bt
