This Sirius Extension Cable is necessary for those installing an RNS315, RNS510 or RCD510 in a 2005.5-2009 Volkswagen and would like to retain your Sirius Radio.
2005.5-2009 Volkswagens which have Sirius Radio installed from the factory gain their signal using a Sirius Module. This module exists underneath the passenger seat. The RNS and RCD series radio do not need this module and need a direct connection from the Sharkfin roof antenna to gain a signal.
Choose 10 feet for vehicles which have the Sirius module under the passenger seat.
Choose 15 feet for vehicles which have the Sirius module located in the trunk.
Choose 20 feet Female to Female if retrofitting a sharkfin roof antenna and need a cable to reach from the new radio to the antenna. One antenna is needed per each connection (I.E. Sirius, GPS)
If your 2005.5-2009 Vehicle's factory radio does NOT have Sirius Radio/Sirius Module underneath the seat, please purchase the External Sirius Antenna which is also available in the Eurozone Store.
