FYI, many folks only use the built in antenna with the 2000C mounted on their yoke, and have no problems with lost
signals. I have mine hooked up with the Lowrance external antenna and have the wires tucked in along the edge of the
windshield. The 'mouse' is tucked in along the edge also, not obtrusive in the least and it causes no problems with my
compass...
