Peripheral Technology’s PXAMG Install and Initial Evaluation

Parts Required:
Peripheral Technology’s PXAMG
Peripheral Technology’s PGHGM5 radio Harness
OVERVIEW
Installation of the Peripheral Technology’s PXAMG
(http://www.peripheralelectronics.com/prodDetails.aspx?strProductID=276) requires access to the back of
the Corvette’s radio to interface with the factory entertainment system. The supplied PGHGM5 radio
harness is basically a “Y” cable which connects to the back of the radio, the factory radio harness and the
PXAMG. The supplied 11 foot iPod cable is then connected to the PXAMG. The PXAMG supports two
AUX inputs and a iPod connection. One available device that can be connected to the PXAMG is a HD
Radio receiver. I did not want the HD Radio interface at this time, so this will just cover the PXAMG.
INSTALLATION STEPS
Removal of the center console is required to gain access to the radio.
Here is an overview of the procedure.
•Flip open the center arm rest and remove the 4 T15 Torx Screws.
•Remove the Blank/F55 cover that is at the bottom of the center console by using a small screw
driver to pop it off.
•Remove the two 7mm Hex bolts that were located under the cover.
•Now grab the boot for the Emergency Brake and pull it up until the boot disconnects from the
center console.
•Remove the two 7mm Hex bolts at the top front of the area just made visible from the lifting of the
E-Brake Boot.
Now you are ready to remove the center console.
•Remove the shift knob by pulling down on the shift boot and removing the screw holding the knob
on (2008 and newer require a different procedure to remove the shift knob which is documented
elsewhere on the forum), Once the shift knob is removed.
•Starting at the bottom of the console trim (nearest to the arm rest) gently pull up on the console
until all of the clips holding the trim in place are out from the dash.
•Once the console is free from the dash, start disconnecting all of the electrical connectors for the
different switches mounted to the center console trim.
This is what your center console will look like.

Now you are ready to remove the radio.
RADIO REMOVAL
•Remove the two 7mm Hex screws that hold the Climate Control Module (CC Module) to the dash.
(The CC Module has a clip on each side that fits into the radio frame). I placed a towel over my
shifter and center console frame to protect the CC module.
•Once the CC Module is removed, start removing the four 7mm Hex screws that hold the radio in
place. Once the screws are removed, pull the radio out and you should see the two connectors
on the back of the radio we need to disconnect.
Here is a picture looking down from the top of the radio at its back.
•Disconnect both cables that have the blue disconnects. One connector will be black and one will
be grey.
•Now plug the PGHGM5 cable into the radio (there will be one plug for the grey and one plug for
the black connector.
•Plug the cars radio harness which was disconnected from the radio into the two plugs on the
PGHGM5.
This is what the connections should now look like.

Now it’s time to put the radio back into the dash. You may need to guide the extra cable and connectors
to the side of the dash in order to fit the radio back in.
Please take note that the radio has a pin sticking out its bottom back that fits into a bracket located at the
back of the dash.
Here is a picture of the bracket the radio “plugs” into
Once the radio is back in the dash, temporary place two screws into it to hold it in place. Now reinstall the
CC Module. Once this was completed, I ran the cable that goes to the PXAMG under the CC Module.

As seen in this picture. (It’s the cable with the electrical tape wrapped around it under the CC Module
between the second and third button from the right)
I now connected the PXAMG to the PGHGM5 cable.
PGHGM5 Connector

Page5of14
PXAMG connected to the PGHGM5 cable
This was then connected to the iPod interface cable and mounted into the space under the CC Module.
The iPod interface cable connects to the 1st DIN connector on the PXAMG. (Note: The four DIP switches
on the PXAMG are in the “OFF” position for correct operation)
As you can see from the above picture, I placed the extra iPod interface cable next to the PXAMG.
At this point, I wanted to test the installation out to verify its operation and functionality.
The PXAMG manual states that the first time the unit is connected to the radio it needs to initialize before
it is operational. This is done by turning the ignition on, then the radio, waiting a minute or so and then
turning the ignition off.
Once the above was done, I connected my wife’s iPod to the interface cable. Turned on the radio and
verified that the AM, FM, XM and CD worked as normal. Once normal radio functionality was confirmed, it
was time to test the PXAMG.

The steering wheel controls for volume Up/Down work as expected and the Up Arrow and Down Arrow

Initial Impressions
Installation took me about 1 hour to complete and test. Once I learned the radio functions needs to control
the iPod, using the PXAMG was easy. Overall sound quality was excellent with good volume and quick
iPod responses to user input. The PXAMG does a good job displaying as much information it can on the
radio screen considering it is hacking itself into the GM Serial Network. The following information is
displayed on the screen.
•Playlist
•Artist
•Song Title
•Length of Song
•Song Time Remaining
•Album
•Genre
Since the above information is only displayed on the top most line on the screen, it is displayed
individually.
The PXAMG charges the iPod while it is connected and will stay in iPod mode until exited out by
switching to another radio function. If the car is shut off while the iPod is playing a song, the next time the
car is started, and the iPod will continue to play from where it last left off.
Once I confirmed the functionality of the PXAMG, I finalized its installation as shown here with Velcro
