This is a Universal Rubber Antenna we have been using in our own cars & builds.
We have found this one to work great as it has a perfect way of mounting in the qtr panel.
This is easy to install. It comes with a 54" Cable that will work with most modern CD units.
Or you can trim the end and tie it in to the excisting BMW antenna wire.
NOTE: 16.5" Rubber Antenna features a replaceable flexible mast and a 54 inch cable and an adjustable swivel base for top or side mount applications.
Select Shorty Antenna as a choice above.
