i have just bought a c class 220 on 2008 its se model deisel and its fitted with an audio 20 but ive been offered an audio 50 from a same year e class will this fit? if not should the audio 20 be ipod compatable if so how?
No the e-class unit wont fit. Audio 20 supports aux input (will simply let you listen to ipod via the car) and the mercedes ipod kit (will let you listen, control, charge the ipod via the car). There is also a new and better aftermarket option called the mCar.
If your looking to upgrade to a sat nav unit you need one from c-class / clc. You can either fit what would have been the option for you car Comand NTG2 or the latest united fitted to MY09> cars the Comand NTG2.5. Some more info on the units here: COMAND - All about COMAND
Comand NTG2.5 has full built in bluetooth connectivity, hard disk based navigation with full 7 digit postcode input, sd card slot, single dvd or optional 6 dvd changer, music register on the hardrive, dvd playback, mp3 playback + more.
Do a search for ntg2.5 plenty of threads about it.
Have the Universal Media Interface on my 2008 W204, gives sat nav, USB and Ipod connectivity. Not sure if this is still available but worth investigating. Have a 16GB USB stick with virtually all my music on it. Enough to listen to for nearly a years motoring
