Is it possible to simply install a HomeLink-enable mirror in an SE Frontier? I see there are third party products but I'm wondering if I can simply buy a Nissan mirror say for a Titan, with HomeLink, and install it. Otherwise, can someone give me a ballpark number for a third-party mirror? I am only interested in the HomeLink aspect, the compass and other stuff doesn't interest me. Am going with a Kenwood DNX-6140 stereo with GPS, XM, iPod interface and backup camera.
