I sold my E350 estate last week as I couldn't get on with it, and picked up an older C220cdi estate, first thing was to fit bluetooth, so decided to go with Pioneer Appradio 2. £350 all in, not bad for a better radio, parrot bluetooth, ipod control, google, sat nav etc. including fascia and fitting harness that also gives steering wheel controls etc. Took around an hour to fit. Next mod is sort the wood trim out!! Will update this thread with my thoughts on the unit as I use it, if anyone is interested?
