I have recently purchased the RDS-Traffic receiver. I live in the Chicago area as well. I was wondering how well the RDS-Traffic receiver works as well as potential quality stations in the Chicago land area to tune into. I do know that the tomtom will tune into a handful of channels automatically, but I was wondering if a specific channel would be better than another. Is the information it receives from the different channels the same, or is one channel better than another? I have only had it for a day and tried it on the way to work and it seemed to work just ok, I was wondering with other people experience with it how accurate is the traffic information as well??
