*PLEASE NOTE: In 2007 AUDI/VW started transitioning vehicles from having dual antenna leads to a single antenna lead. Please double check your plugs if your vehicle is a 2007, depending on which part of the year the vehicle was manufactured it may have dual or single.

*PLEASE NOTE: For A4 and RS6 the first model year listed is a split year. In these years these vehicles may have either a CAN BUS or MOST BUS system depending on which time of the year the vehicle was manufactured. In years following these vehicles should have a MOST BUS system.
 
If your vehicle has a single antenna lead and you are putting in a receiver with dual antenna leads or vice versa you can use an antenna splitter. These can usually be purchased for around $15-$20. Please search for "Terk Antenna Splitter" and you should be able to find one.
