Could you tell me if this unit (CTVRNX001) made by connect 2 should work on my tuner list head unit via the cd changer port (blue) and allow me to play my ipod? Would it need to be a specific model tuner list player as I cannot see a function on the player for a cd changer and there is nothing in the manual. People are telling me it should work but by pressing the source button on the steering wheel control stick but still no joy, please help as this is turning into one of those jobs thats bugging me. Cheers
