Finally after three months I'm going to install my navi... I purchased a Kenwood DNX6140, and a Kenwood KSC-SW10 sub for my truck. This weekend is install time. We were reading the driections from Crutchfields and they talk about the speed sensor wire. Any input as to where we can find it? And one more question.. kind of... where did you put the stupid little antenna for the XM and navi? I hate those little black things. wonder if I could hook up the XM to the existing XM antenna? thanks for any input...
