INSTALLATION
OVERVIEW
1. Remove radio trim panels to gain access to radio mounting screws.
2. Remove the radio partially to expose rear connectors.
3. Unplug factory connectors from radio and then plug them into Lockpick harness connectors.
4. Plug in Lockpick harness connectors to radio.
5. Connect camera(s) power and ground if installing aftermarket system(s).
6. Reassemble and enjoy.
This written guide will detail the connections for the Lockpick harness and provide reference for general installation and
operations. The GMX550 is universal for many different GM models and individual dash disassembly is not addressed in this
manual.
1. Start with the car and radio turned off. The GMX550 is designed with a dual “T” harness, equipped with factory male
and female connectors for direct connections to your screen. With access to the rear of the screen, unplug the
matching Black and Brown connectors and plug them into the female connectors of your LOCKPICK. Then plug the
male connectors of the LOCKPICK harness into the earlier factory locations. The connectors are keyed and cannot be
plugged in to the wrong location. For most installations, the disassembly needed to get to the rear of the screen will
consist of “popping” loose the trim around the face of the radio to expose the 7mm or 10mm bolts holding the radio in
position. Remove the bolts and the radio can be tilted rearward to view the connectors needed. The trim around the
face of the radio is held in place with spring loaded friction locks which sometimes can require extra pressure to
release. Videos and have been provided on the CoastalEtech.com website to provide you assistance as well as details
and photos for Cadillac Escalade installations.
2. The GMX550 Lockpick is a simple Plug-N-Play interface however additional wiring is labeled and available on your
Lockpick harness. These connections may be used for your aftermarket accessory power needs.
RED – 12V ACC power output (Limit 1 amp) This is an output, do not connect to vehicle wiring. If your accessory
requires more than 1 amp, use this power output to control a relay connected directly to battery power.
YELLOW – 12V constant battery power output
BLACK – GROUND connection
ORANGE W/BLACK stripe – 12V rear camera power output (use this power source for your aftermarket rear
camera or for full control of your factory camera see step 3 below)
RED W/BLACK stripe – 12V ADDITIONAL camera power output (use this as the power source for front/left/right
view camera(s))
3. If you have a FACTORY REAR VIEW CAMERA and would like to be able to view and control it when in DRIVE,
extend the ORANGE W/BLACK stripe 12V REVERSE wire labeled in your GMX550 harness. A crimp connector is
already attached for your convenience. Route the wire along the edge of the console and down to the small silver
module under the passenger seat. Slide the seat all the way back to view the connector on the front or side edge.
Unplug the connector and cut the Blue wire pictured in the photo below (end wire, left side, from the back of the
plug). Attach the ORANGE W/BLACK stripe GMX550 wire to the blue wire on the vehicle connector. The other cut
end of the wire in the factory harness should be insulated and left disconnected. Do not connect the Lockpick Orange
w/black stripe wire without cutting the BLUE factory wire or improper operation will occur. Also, early year Enclave
and Acadias may place the camera module in the rear instead of under the passenger seat. Refer to website at:
http://coastaletech/Acadia.htm for installation help. For 2008 and later H2 and all 2009-11 vehicle installations, extend
and run the GMX550 BLUE wire to the back of the vehicle and connect directly to the rear view camera connector
blue wire. Refer to website at: http://coastaletech.com/Hummer.htm for example install pictures.

unique and keyed so you cannot plug
them into the wrong location. Insert
the connectors fully until they click
or are locked into place.
4. For all aftermarket cameras, plug in the video connector from your camera to the labeled input (front, rear, left,
right) and connect all power(s) connections to the RED W/BLACK stripe camera power wire on your GMX550
harness. Connect the ground(s) for your camera power to the Black ground connection on the GMX550 harness.
OPERATION
To activate the GMX550 LOCKPICK, press the MUTE (VOICE) button on your steering wheel (4) four
times within 4 seconds as demonstrated below. Text with menus and options will appear on your
instrument panel.
The menus of the GMX550 are controlled using your steering wheel NEXT UP ▲and NEXT DOWN ▼

The GMX550 Lockpick text is viewed on the instrument panel and is compatible with ONSTAR and warning
messages. If a door is opened or a vehicle fault occurs while the Lockpick text is on the screen, the Lockpick allows
the OEM messages to have priority. Also, during the viewing of the Lockpick text, or while scrolling through the
Lockpick menus, the vehicle may have moments when the viewing of the Lockpick text is not allowed and the
Lockpick text will not immediately appear or may flash once before staying on. This is normal and is part of the
design.
Immediately after the vehicle is turned on, the radio may download large amounts of information from XM radio
services. During these first moments, various communication systems in the vehicle are at capacity and the
Lockpick does not interfere with this process. Therefore, for best results allow approximately 30 seconds after
starting the car before activating and accessing the Lockpick instrument panel text.

**During the time that you are using the 60 second NAV IN MOTION feature to input an address,
active map tracking is not occurring (if you switch back to the map, the map will not be moving or
pinpointing your exact location). Standard navigation functions will automatically return after 1
minute or you can turn off the NAV IN MOTION function using your steering wheel buttons to
immediately resume normal nav operation. Also, if you are using OVERRIDE MODE 1 or 2, the
GMX550 needs to block navigation tracking when you activate the DVD IN MOTION function.
Simply turn off DVD IN MOTION if you switch back to the map during DVD play for normal
o
p
eration.
USB UPDATING
(make sure module is also connected to Lockpick harness and vehicle)
Your Lockpick interface includes the ability to be updated via a USB connection to a PC. Located on your
Lockpick module is a common mini USB jack which can be connected to the USB jack on a laptop computer using
a standard USB mini to USB connection cable . These cables are the same ones used to connect most
camaras/camcorder/phones, etc. to a computer and are available in virtually all electronic departments.
A software program is available for download and installation on our website at
www.coastaletech.com/usbupdate.htm Download the application software and save it to your computer. Open the
folder and select the SETUP file to install the FIRMWARE UPDATER program on your computer. When
prompted, install the USB drivers included in the UPDATER software. On our website we provide updates and
changes that will use the FIRMWARE UPDATER program to allow simple updates to your Lockpick module.
To perform an update to your module, download and save the desired Lockpick update from our website.
Make sure the module is plugged into the Lockpick harness and connected to your vehicle with the key off. Plug in
the USB cable to the Lockpick module and your computer. Wait while your computer recognizes the new device,
then open the FIRMWARE UPDATER program on your computer and when prompted, browse to the location
you saved the desired update. Start the update as directed in the software and do not stop the process once begun.
After completion, disconnect the USB cable and start the car to use and explore the installed firmware changes.
Module DIP Switches:
•The Lockpick module is equipped with programming DIP switches which allow the user to select additional
options which may be necessary for proper operation in specific vehicles.
•For standard installations, all DIP switches should be left in the UP position.
•If the switch settings are changed while the module is still plugged in, the Lockpick will ignore the changes
until it has been unplugged and then plugged back in.
•For early build 2007 Cadillac Escalade vehicles (manufacture date 2005-early 2006), DIP switch 1 should
be placed in the DOWN position with all the rest left in the UP position. You can determine your build date
by looking at the driver door tag and noting when the vehicle was manufactured. This special Lockpick
programming setting will allow Lockpick text to display on the instrument panel on the early build 2007
Cadillac Escalades.
•Place switch 5 Down to block factory DVD video in motion. With switch 5 Down, the GMX550 will not
allow the DVD to play on the front screen while the vehicle is moving.
ENJOY YOUR LOCKPICK!
