Summary: I have used my iWay 500C for the last two years and believe that I have gotten pretty good use out of it, but there have been some serious issues:
1. I bought this unit because it was waterproof and rugged (I mounted it on my motorcycle as well as used it in my car). However, the iWay overheats on a regular basis. During the summer in the car, it frequently warns of shut down, even though the temperature in the car is not excessive (air-conditioned).
