For what it's worth, I bought an antenna adapter on eBay that was supposedly for the XC90, but didn't fit the plug at the radio location that mated with the ICM at all. I saw that the essential concentric connector in the eBay plug was similar to the two antenna connectors in the original plug, so I "liberated" the connector from the plug shell and jammed it into the vehicle plug. I have no idea which of the two similar plugs in the vehicle plug I selected, but my FM reception is good, with the only FM station I listen to here in San Diego. That hadn't been the case with some other vehicles I've had, since it's a relatively low powered college station. The item was sent from Slovenia, so I suspect it was intended for a different market-version, but the two ends of the pigtail ended up working, for me.Thanks for the reply. I want to use the "stock" FM antenna for an after market 2 DIN radio. I saw some DIN antenna adapters for Volvo and was wondering if I could actually just plug one in. .
