I've used the BlueDriver on both my 2006 and 2007 Crossfires and it works fine without any special configuration. Last year I replaced both car batteries with AGM batteries. I did not bother to provide alternate power to the car computer to save the OBDII readiness status. That will never happen again. I had to drive both cars through the mercedes drive cycle procedures to get the OBDII readiness for the annual state emissions inspecition that is done with the safety inspection. As is expected, sometimes that takes multiple tries to get a specific monitor to successfully complete. The BlueDriver was just quick and easy to use for that purpose.

Sometime over the next week I will test it on the 2004 Crossfire to confirm it works on it as well.
