I know that there are GPS extension cords with a female/female FAKRA plug to connect to the RNS-E and to the OEM GPS antenna but are there female/male extension cords as well? I'm thinking of extending the GPS from the OnStar harness that ends under the passenger seat but IIRC it's a female plug that went into the OnStar box. What I would need is a male to female extension, probably 2m/6 feet or so. Does anybody have a source and / or part number for this? Or are there connectors that allow you to connect two female plugs together?
