Hi-

I have a 2001 E55 with the stock timeport phone... I'd like to upgrade
the phone and keep the functionality of the steering wheel controls
and the built in microphone and speakers.

So far I've come across two options:

1. Argos bluetooth adaptor: http://www.eiskits.com/

2. or a mercedes bluetooth adaptor.

Does anyone have any experience with either of these? Or does anyone
know of other (maybe cheaper?) solutions?

Thanks,

Jeff Bisonett
