If you need to remove the mount, carefully lift the adhesive pad with your fingers or a
spoon. Warming with a hair dryer for several minutes will help soften the adhesive.

To install the swivel mount, first find a suitable location.  The swivel mount’s adhesive is very 
strong and may be difficult to remove.  Do not install this mount on leather surfaces and make 
sure the air temperature is at least 60°F.

Clean the mounting surface with the 
surface preparation kit.  Peel away the 
adhesive liner.

To install the vent mount, find a horizontal vent that is strong enough to hold your NeXus 
and its car cradle.

To remove the vent mount,push it into the vent and lift upwards slightly to release the 
mount’s hooks from the vent vane.

Peel off adhesive liner.

Either orientation may be used.

For best FM Modulator performance, you must locate the satellite radio antenna 
in a location that is in close proximity to the vehicle’s FM antenna. 

Avoid kinking, crimping, twisting or chafing the cable.  Use pre-existing wire 
channels when possible.

For option 1 and rear mounting locations, route the cable into the trunk as 
shown.  Always cross the weather seal at the lowest part of the trunk to reduce 
water leaks.  From the trunk, route the cable into the passenger compartment 
through available wire channels and then along the floor under the door jam 
trim or under the carpet to the front of the passenger compartment.  Do not 
leave the cable loose in the passenger compartment where it is likely to be 
damaged.

For option 2 and front mounting locations, route the cable along the door jam 
and into the vehicle as shown.  Route the cable across the weather seal near the 
bottom of the door to reduce water leaks.

This XM Receiver offers the listener a variety of options for connecting XM Satellite 
Radio to your vehicle’s FM radio.   XM research and lab test results show that using a 
vehicle cassette adapter can best maximize the relationship between the best sound 
quality and ease of installation.  If your vehicle kit does not include a cassette adapter, 
one should be available at your local retailer or visit www.xmradio.com, click “Shop XM 
Radio.”

Using a cassette adapter for audio is the most popular and best sounding solution.  
Please follow steps 1 through 4 below for mounting the satellite radio antenna and 
securing the XM receiver and cables.

A wired FM installation kit is available from your retailer for professional installation.  
See your retailer for details.  This solution is recommended if you cannot get 
acceptable performance with the wireless FM modulator.  

The XM receiver is equipped with a FM modulator which can transmit the XM audio 
to your car’s FM radio without wires.  

 

Please note that the cables and antenna wire that has been supplied with your device 
are supplied with permanently attached ferrite beads.  It is the responsibility of the user 
to use the cable and antenna wire with the ferrite beads.

The user is cautioned that changes or modifications not expressly approved by XM 
Satellite Radio, Inc.  can void the user’s authority to operate this device.  

This device complies with Part 15 of the FCC Rules.  Operation is subject to the following 
two conditions: (1) This device may not cause harmful interference, and (2) this device 
must accept any interference received, including interference that may cause undesired 
operation.

This equipment has been tested and found to comply with the limits for a Class B digital 
device, pursuant to Part 15 of the FCC Rules.  These limits are designed to provide 
reasonable protection against harmful interference in a residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if not 
installed and used in accordance with the instructions, may cause harmful interference 
to radio communications.  However, there is no guarantee that interference will not 
occur in a particular installation.  If this equipment does cause harmful interference to 
radio or television reception, which can be determined by turning the equipment off 
and on, the user is encouraged to try to correct the interference by one or more of the 
following measures:

-   Reorient or relocate the receiving antenna.
-   Increase the separation between the equipment and receiver.
-   Connect the equipment into an outlet on a circuit different from that to              
     which the receiver is connected.
-   Consult the dealer or an experienced radio/TV technician for help.

IMPORTANT:  For best wireless FM Modulator performance, you must locate the 
satellite radio antenna in a location that is in close proximity to the vehicle’s FM 
antenna.  

For example, with reference to Figure 1, if your FM antenna is located on a rear 
fender or top of the roof, mount the XM antenna near the rear window location 
(option 1).  If your FM antenna is located on a front fender, mount the XM antenna 
near the windshield location (option 2).  Remember, the closer the satellite radio 
antenna can be to the FM antenna, the better the wireless FM reception and sound 
quality will be.

In order to optimize the operation of the wireless FM modulator, follow the 
installation guidelines outlined in steps 1 through 4 below:

First, determine the proper location for your satellite radio antenna based on the 
following criteria for your specific vehicle:

You must locate the satellite radio antenna on the top of the roof either in front 
of the rear window (option 1) or behind the windshield (option 2).  The satellite 
radio antenna will perform best if magnetically attached to a steel surface with 
an unobstructed view of the open sky and minimum of 3 to 6 inches of metal 
surrounding the antenna.

When routing the antenna cable along the windshield or rear window, tuck the 
antenna cable under the window seal to maintain a professional looking 
installation and to avoid loose wires on the exterior of the vehicle which are 
susceptible to damage.  Follow the interior cable routing diagram depicted by 
dashed lines in Figure 1 where possible.

Be sure to locate your car cradle and receiver below the top of the dash in your 
vehicle to keep the product within easy reach while driving.  Choosing a lower 
location in your installation should also make it easier to manage the cables and 
achieve a more desirable appearance when the installation is completed.  A lower 
location for the receiver in the vehicle will ensure that the installation does not cause 
interference with other FM radios outside the vehicle. 

See illustration below (Fig 2) and be sure to locate your car cradle within the shaded 
area.

Fig 2

Once you have plugged the power 
and antenna jacks in to the car 
cradle, use the included cable 
organizer as shown in figure 3 to 
improve the overall appearance of 
the installation. 

Re-use the cable twist ties that were 
provided with the power adaptor 
and car antenna cables and always 
be sure to gather, bundle, twist tie, 
and secure any excess cable 
remaining after determining the best 
location for your satellite radio 
installation.  

For example, secure the excess cable up under your dash board, between the seat 
and the console, or on the floor under a seat or floor mat.  This will help to prevent 
the excess cable from interfering with the everyday use of your vehicle, improve 
the appearance of the installation, and avoid any undesirable accidental damage 
to the cables that might result in loss of power or satellite signal.   

For wireless FM modulator installations, securing and tie wrapping the excess 
cable is important to reduce background hissing noise.  Be sure to choose a 
location carefully by taking notice of how doors and trunks open and close, as well 
as how seats move when they are adjusted so you can be certain there is ample 
clearance provided for the cables.
