can i get sirius and rear entertainment system after
 

i purchase x5? would it cost me alot more to get and install? i figure if i could save some money on my monthly payment and i would get these later... $2395 is about $45 extra a month in payments for 60 months is $ 2700 extra im paying = $5095 .. i already have a sirius unit and lifetime plan but i think it would look better w/o the unit on my dash.

BMW do sell a retrofit rear entertainment system. It has two screens mounted up behind the headrests which you could argue is better than the screen down between the seats. I would investigate third party alternatives too.

I don't know about the rear entertainment system. But the Sirius unit is much more expensive when done after purchase. (~$900)
