Question for the collective: Looking at putting a Nav IV onto an R1200GS. Unlike the SP 2720 I have at the present, it appears that the Navigator cradle (as well as the 660 cradle) are "hard wired," meaning that the leads from the cradle to the power supply don't unplug. That appears to mean that while you can disconnect either GPS receiver from the cradle, the cradle stays on the bike permanently, whether you have it clamped to the crossbar or to some flavor of RAM mount. Have I sorted this out correctly? Even if I have, has anyone found a way to pull the receiver and the cradle while leaving the wiring in place? Thx!
