Just finished a wonderful 1800 mile trip with my FX45. What a wonderful ride! I incurred a problem with the laser speed control. When it would rain I could not set the speed. Figured that maybe the unit had gotten some road "sludge" on it or something and that was impacting how it functioned. I could bypass the laser control and everything worked fine. I did not think much of it until the last two days we have had light rain and mist off and on. When ever it was misting or raining, I can not engage the speed control with the automatic distance control function. Anyone experienced anything like this or have some insight to what might be going on? I have about 2500 on the speedo. TIA.
