I just found a Pioneer X910BT for as good price. I Purchased the FRD-1 and the SW-1 Adapters to keep the SW controls and Sync. I follwoed the instructions but nothing worked. I put the Fatory Head unit back in and now it doesn't work. No Display or sound. I checked the fuses and the connections but nothing. Any clues? Thanks

Try running a wire from the battery to the 12v+ wire on your head unit and see if it powers up then. Also, check your ground.
