iPhone, RNS-E and DAB - Best options?
I've just got my first iPhone, and am exploring the best options for integrating it with the RNS-E in my 2007 A4. I also have a Revo Incar DAB radio, with FM modulator.
The RNS-E has Bluetooth, so that covers off the phone connectivity, but I obviously want to play music too. I have a 6-CD changer in the glovebox (which I don't use) so one possibility would be to swap it out for an Audi iPhone controller, but I understand the Audi interface is a bit limited. I don't have a multi-function steering wheel, so
I tried an X-Carlink while ago, intending to use its auxillary port to feed the Revo directly into the RNS-E and dispense with the FM modulator. This worked fine, but the presence of the X-Carlink massively degraded the DAB signal from the aerial, so I had to dispense with it. It might be the one I had was faulty, but I don't want order another one just to find I have the same problem again.
So, I think that leaves me with the option of a Dension Gateway. Ideally, I'd still like to direct the Revo through the aux-in at the same time as hooking up the iPhone, so I think that means I would need a Gateway 500. But I'm also worried that a Gateway could interfere with the DAB signal.
Can anyone offer me the benefit of their experience and suggest a best option, including perhaps a solution I haven't already thought of?
