I went from the cd400+ to Navi 950 intellilink
The roof sharkfin was a dummy on my GTC cd400, the Navi950 sharkfin is for the satnav and intellilink
The DAB still uses the same type amplifier, as does the FM. But they might not be getting powered up by the Navi 950
Also on mine there is a splitter on the aerial cables, located under the dash
ps: also worth checking the aerial connections, driver side - behind kick panel, are connected correctly.
