MOUNTING
Find a flat 5”x5” square surface with a minimum of 6” unobstructed clearance behind it for the
chassis and all it’s necessary wiring.
1.
Once you have determined a mounting location, cut a 3” diameter hole (77mm). For best
results, use a 3” hole saw and powered drill. Think before you drill!
2.
Route all power, ground, audio signal, SiriusXM Radio Tuner cables, etc. to the mounting
location. Allow additional cable length to accommodate final connections. For more
information on how to install the SiriusXM Connect Vehicle tuner, consult the installation
guide included with the tuner.
3.
Attach two provided U-bracket studs to their respective locations on the back of the
HMR-3 chassis. Hand tighten the studs with an adjustable wrench or pliers.
4.
Route the power, ground, audio signal, SiriusXM Radio Tuner cables, etc. thru the hole.
5.
Insert the chassis of HMR-3 and wiring through the hole.
6.
From the backside of the mounting surface, slide the U-bracket over the two studs on
the back of the chassis and attach the supplied nuts. Hand tighten the nuts with an
adjustable wrench or pliers. If the U-bracket is too long, break off one section of each leg
until the U-bracket secures your HMR-3.
7.
Complete all electrical and cable connections. Refer to the following wiring diagram for
electrical and cable connection details.
