I have found that both my cars when BT is on and syncing w/ the phones can cause the PDC and Backup cams and the accept screen to be delayed. When I turn off the bluetooth on the phone and it is not trying to sync the system run A LOT faster and there is no delays. I have spoken with my SA who is very konwlegable and told him my findings and he said that they have experienced the same when approached w/ these concerns. These are just my .02 and findings w/ a lot of testing
