I recently installed my X710BT and performed the bypass using the relay method per instructions found here and on the U-tube video. When I tried to play a DVD for the first time I have received 3 different error codes as I repeatedly put in different DVD's . I got error code 17, code 12, and code 11. Can't find any reference to these in the manual. Does anyone know what they mean?

X710BT does not play DVDs. only CDs. you need the X910BT if you want to play DVDs.
