I put an after market radio in my truck that also hooks to the OBD port, it is similar to the Edge Insight as far as what it displays. I thought it was pretty cool at first and was a feature I would use when towing and I did the first few times but since I drive a gasser the only things that really matter to me are engine and trans temps. Both of those are displayed on the dash so I haven't used the radio feature in quite a while. Now if I had a diesel it would probably be different.
