hybrid tv install problem

[ColinR32]

Firstly hello all as a newbie,

i hae my self a 2005 A8 3tdi, absolutey lveycar cant fault it, and certainly couldnt part with it now i have had one,

the car came wih analouge tv so after days of browsing the net i bagged myself an audi hybrid tv tuner withpart number 4E0 910 148D

now after i instaled this unit is where the problems start.

when i press the CD/TV butto and then followed by the source button the only option tha comes up is the cd changer, no tv option.

i amlucky enough thave the genuine VCDS cable and have done th programming and coding ect butstill no luck

i have seen that the mmi software is 0900 which i belive is pretty dam old, could this be he problem?

any help at all is greatly accepted
