OK, if you're a "neatnik", this might not work for ya.........but if you are taking an extended trip and want some radar protection, you might try this. I have an '09 Ultra Classic CVO. A couple of months ago, I took a trip and used the cigar lighter inlet for power and stuck the suction cup bracket onto my windshield toward the left side just above the left-hand windshield bag (of three). With a male section of velcro on the bottom of the detector and the female section glued to the top of the left-hand bag lid, the detector held on just fine and was not gonna shake off.
Problem became apparent when I got caught in a thunderstorm........didn't take more than 5 minutes of heavy downpour and the Escort went t*ts up.....blank screen, nada.
So, for my Sturgis trip, I sent the Escort in to be repaired (new mother-board), and when I got it back, I took a zip-lock sandwich bag and made a slit for the suction-cup bracket and another small cut in the side for the power cord connection and another cut in the bottom of the bag so my velcro connection could be maintained........This worked OK, got caught in several storms, but no problems with water due to the baggie enclosure.
Did it look a little "hokie".........YUP, but it gave me the warnings I was after and no tickets............
