Satellite Radio Installation Instructions for BMW Z4 Roadster
03+ with Analog DSP (E85)
Before you begin the installation process, it is IMPERATIVE that you read
and understand the following information. We also recommend
disconnecting your negative battery terminal.
• You will need the Satellite Radio ID number to activate the radio. This
number is always located on a decal somewhere on the satellite
radio module. Write this down before installation begins, as it can be
covered up by Velcro once you install the module.
Tools Required for Installation:
• Panel Removal Tool
• Torx T20 (Ashtray Assembly Removal)
• Wire Cutters/Crimpers
• Metric Allen Key Set
• Brain
Accessing Factory CD Changer Wiring – The wiring we’ll be working with should
be very easily located. However, we have encountered a few Z4’s with the wiring buried
deep within the center console which required complete removal of the factory center
console. If you do not find the wiring within a few minutes, you may want to have your
dealer access the CD changer wiring for you. There will likely be a cost associated with

Once you’ve removed the floor panel, the battery will also be revealed. Go ahead and disconnect
your negative battery terminal.
2) Now, we’ll need to remove the plastic fasteners that secure the upper layer of carpeting along the
floor. There are two of them, one on either side of the carpeted panel.
3) Now, we can fold the carpeted panel along the rear wall back, and we’ll be looking for the
rectangular pass-through into the cabin. It’s about 6” up from the bottom of the floor, and directly
in the middle of the rear firewall. We will be looking for two wires, one 3 pin connector, and one
coaxial connection.
4) Both the 3 pin and Digital Coaxial connector will be found tucked into the rectangular
entrance into the cabin shown below. They can be tucked quite tightly in here, so you may
have to fish around a bit to release them. They may be found together or the coaxial cable may
