It did fix the call button problem as well although we are not sure why. In this case we are just glad it worked. This car has no RCB or at least the one that slides in beside the LCB and CUB card. It had a slot for one though. It has an LCB,CUB and SCIO and then about 6 of the RS cards along the top. Maybe the other car has one but I don't recall seeing it.
