"I was very glad that Roger's Stereo put me in touch with JJ Langguth at K40 when I was considering my purchase.  JJ was able to help me understand the RL360i's benefits and also helped me understand why not having a database of red-light cameras alerts was a benefit.  I'm looking forward to using the system on the road and I feel very comfortable that I will be able to use it effectively."
