Evening Chaps,

I am hoping I can get some answers on upgrading the Navigation system in my 2002 L322 RR. I have already read the dozens of threads regarding iPod connectivity and Bluetooth, but I am in a quandary as to the level of upgrades.

My car already has the standard Navigation system with the telephone – I seek some advice as to what I need in order to achieve the following without replacing the head unit (the main reason for this is that I want to retain the Silver finish like the rest of the centre console):

1. iPod connectivity while still retaining the CD changer functionality (some suggest Alpine KCA-420i, but from what I have been told it is not compatible with the iPhone 3GS or 4).
2. Bluetooth connectivity
3. DAB Radio upgrade
4. Digital TV (I already have the standard analogue tuner, which is not very good)

Many thanks in advance,
