Fuses
When replacing a fuse, make sure the new fuse is the correct type and amperage. Using an
incorrect fuse could damage the radio. The MPX6411 uses one 15 amp fuse located below the
wiring connector (15 amp fast blow ATO).
Reconnect Battery
When wiring is complete, reconnect the battery negative terminal.

Connecting the Satellite Radio Receiver (optional)
Before you can listen to XM
®
satellite radio, you must install the XM
®
Direct Receiver and
antenna (purchased separately). The XM
®
Direct Receiver is the central data receiving
equipment required to process the satellite signals from the external antenna. It is typically
installed in the dash, under the seat, or in the trunk or rear of the vehicle. Do not mount the
XM
®
Direct Receiver near a heater vent or where it can be exposed to extreme temperatures.
In addition, when running the wire for the external antenna do not kink or pinch the antenna
cable. A sharp 90 degree bend or slight "nick" to the outer cable sheath will cause signal
degradation. The wiring diagram on page 3 will help you identify the proper connections.
INSTALLATION
This unit is designed for installation in cars, trucks and vans with an existing radio opening. In
many cases, a special installation kit will be required to mount the radio to the dashboard.
These kits are available at electronics supply stores and car stereo specialty shops. Always
check the kit application before purchasing to make sure the kit works with your vehicle. If you
have trouble locating a kit or need installation assistance, contact Technical Support at 1-800-
323-4815 from 8:30am to 7:00pm EST Monday through Friday and from 9:00am to 5:00pm
EST on Saturday.
Universal Installation Using Mounting Sleeve
1. Remove the detachable front panel, if it is attached to the chassis, by pushing the
“Release” button.
2. Slide the mounting sleeve off of the chassis if it has not already been removed. If it is
locked into position, use the removal keys (supplied) to disengage it. The removal keys
are depicted on page 5.
3. Check the dashboard opening size by sliding the mounting sleeve into it. If the opening is
not large enough, carefully cut or file as necessary until the sleeve easily slides into the
opening. Do not force the sleeve into the opening or cause it to bend or bow. Check that
there will be sufficient space behind the dashboard for the radio chassis.
4. Locate the series of bend tabs along the top, bottom and sides of the mounting sleeve.
With the sleeve fully inserted into the dashboard opening, bend as many of the tabs
outward as necessary to firmly secure the sleeve to the dashboard.
