i can't swear to this, but i don't think there will be any other parts i need to order.
whatever got installed before for my old 8800 is still in and under the dash so i'm hopeful this new part will (either alone or in combination with stuff already there) have everything i need to accommodate the bold later
sorry i can't answer authoritatively; am not very techsavvy
PS, here's the kit i currently have for the 8800 (now 8820) and it doesn't seem to have much more BlackBerry 8800 Series Bury Comfort Cradle Car Kit
UPDATE: now i'm thinking the pedestal may somehow have come separately. (maybe i bought in addition to whatever cradle i got for an earlier 8700 handheld.) sorry it's so foggy and i haven't been any real help
