I have an '05 MCS
with sat nav, MFSW, BOOST radio with single CD player (ridged volume control) plus iPod 3G and Icelink plus.
Like you the split screen shows a lot of ID3 tags and from time to time the map. On other occasions I get no ID3 tags and just regular map info.
Selecting playlist thru' the radio buttons works as does selecting tracks from tth MFSW.
I figure this is about as good as it gets ?
btw Icelink plus is running V22b2 and my satnav also has the latest FW installed.
Hope this data point helps you out.
Mikey - any comments / pointers ?
