Hi guys, long time no see I've helped with a install from a Concert 2 (concert cd-player) and the strange part is that the radio reception is not working. We have a adapter from the "50ohm ISO" to fakra, but not from diversity to fakra. (see kufatec picture) Should not the radiosignal be transmitted even if the diversity is not connected? We have ordered a new adapter from Kufatec (same picture) but I wanted to be sure if there is nothing else we should have been thinking of Btw, the car also had the trunk based navigation, this is disconnected. So is the Telematics. Could there be a "radio signal" cable (or TMC box?) that I havent disconnected? AFAIK there was no radio signal to the TMC box, and there also was only on the RNS-D?
