Audi A8 - TV Module/PS3/Ipod Etc/MMI

Sorry about multiple threads but i couldnt fit them in same title.

Question 1 - i wish to remove the lock on the TV so its viewable on the move, is this possible using the cars port or do you have to install a module to bypass the system?

Question 2 - can you install a Ps2/Ps3 under the option External AV source?

i have been quoted £220 to install the TV module and install a red/yellow/white phono cables within glovebox so i can plug an external source and select the above item.

can you access this external AV source from the boot? when selecting this option nothing happens so i am a bit in the dark.

Question 3 - TV tuner, i have been ifnromed you can upgrade to the newer TV unit, however this unit is big bucks so i dont intend to do that. can you install a freeview/free sat unit to watch multiple channels?

Question 4 - Can you upgrade the look of the MMi to the latest style 55-59?

Question 5 - i would also like to be able to plug an ipod in and to be dispalyed on MMI screen, is that possible? i have seen you guys do it on 05-55 but what about pre that year?

car is Audi A8 4.2 with bose system
