After reassembling the bike, I went for a short ride to check out the changes. The power connector for the GPS works just fine, no surprise there. Mounting the GPS on the dash does prevent a lot of vibration, but I will have to experiment with the various mounting arm lengths to get the right position. Because it is closer to you and lower, it needs to be tilted up more and that makes the sunshield less effective. The audio cable works fine and the stereo XM radio sounds really good.
Now for the really important mod, the turn signal cancel mod. Going down the road at about 45 mph, hit the right turn signal button and it blinks 10 times and cancels. OK. Stop at an intersection, hit the turn signal, and make the turn – the signal cancels when the bike is upright again. OK. The previous functionality is still there. Now, going down the road at 45 mph, hit the signal button. But when it has blinked 7 times, briefly hit the foot brake. It continues for 10 more blinks and then cancels. PERFECT. Now for the real world test. Going down the road at 45 mph coming up to an intersection, hit the turn signal well in advance. Now, apply the brakes as you normally would, turn signal still blinking. Stop, and release the brakes. Turn signal still blinking. Make the turn, it cancels when the bike is upright again.
JUST THE WAY IT SHOULD WORK.
