Frequently asked questions and troubleshooting
1.
My vehicle has XM module but subscription has expired. Will the GM3x-
HF work?
YES.
If subscription has expired, the module XM/AUX input can be used to
connect and play an audio device (Mp3 Players, iPod, DVD, iPad etc.)
Aux.
input option is
not available
to active subscribers or vehicles with remote
CD changer or RSE.
2.
I’m not the original owner and don’t know if vehicle has XM module.
How can I find out without ripping it apart?
Turn radio “ON”, press “BAND” button repeatedly to cycle through
AM/FM/CD/XM1/XM2. If only AM/FM is displayed, vehicle does not have
required XM module.
3.
Does the GM3x-HF work on all GM radios?
Works on Navigation and non-Navigation GM Class-II radios with XM module
with or without subscription
or remote/external CD changer. (Changer
built-into radio is not external/remote) or RSE.
4.
Can I control Smartphone music from radio buttons?
NO;
you
must continue to use audio device built-in controls or included
control button and/or voice commands to operate audio device.
Volume button on radio can be used to set playback level.
5.
What do I need for the GM3x-HF to work in my vehicle?
For the GM3x-Hf to work, your vehicle must have
at least one
of the
following factory options:
XM module
(With or without subscription),
external/remote
CD changer
or
RSE
(rear seat entertainment-DVD)
6.
How do I listen to factory option (XM, or remote CD changer or RSE)?
Press BAND, XM or CD/AUX button on radio to enter XM or CD changer or
RSE mode (if not already) then press control
button 4 times. These
instructions also apply to enable Aux playback option (instead of
XM/CD changer)
7.
Where is the best place to install control button/mic?
We found that having the control button/mic mounted higher on the dash
worked best, but users can experiment with different location and decide
which works best for them.
8.
Will the stereo mute when I receive or make a phone call?
This system will mute if radio is in “XM”, “CD changer” or “RSE” mode
(Bluetooth mode). If in AM/FM mode, radio will not mute and you must also
switch to Bluetooth Mode (XM, RSE or External changer)
9.
How do I pair a second phone to module?
In order to pair a second phone make sure no other phones are connected.
Once Bluetooth is disabled on first device, module will be ready for pairing.
10.
Will I be able to use module USB port to connect and play music from
flash drives?
No.
The USB port is for charging only.
11.
My radio has a built-in 6-CD changer. Will the GM3x-HF work?
As the name would imply, external or remote CD changer refers to changer
mounted in remote location (e.g. armrest, glove box, trunk, hatch, under
seat etc.)
The built-in changer to factory radio (6-CD changer radio) is internal
and not the external changer referenced herein. Remote or external
CD changers are installed in glove box, armrest, trunk, hatch etc. and
required for module to work as described.
