Hello,
2003 Ford F150 Super Crew
I current have a Sony CDX-GT510 hooked up to front and rear door speakers,
rear amp and sub using Metra-70-1771. Everything works great for the past 7 years. Figured it was
time to upgrade the head unit so I purchased a CDX-GT575UP.
Before the installation, I checked all the wiring diagrams and mapped out the following.
COLOR CDX-GT510 CDX-GT575UP Metra-70-1771
Red 12v ASSY 12v ASSY 12v ASSY
Yellow 12v BATT 12v BATT 12v BATT
Orange/White Ilumination Illunimation Illumination
Black Ground Ground Ground
Blue/White AMP Remote AMP Remote NONE
Blue ANT Remote NONE NONE
Light Blue ANT NONE NONE
Front Right (+) Gray Gray Gray
Front Rignt (-) Gray/Black Gray/Black Gray/Black
Front Left (+) White White White
Front Left (-) White/Black White/Black White/Black
Rear Right (+) Purple Purple Purple
Rear Rignt (-) Purple/Black Purple/Black Purple/Black
Rear Left (+) Green Green Green
Rear Left (-) Green/Black Green/Black Green/Black
Since everything matches up, easy swap so I figured.
I removed the Metra Connection then removed one wire from the CDX-GT510 harness
and soldered to the CDX-GT575UP one at a time. Cannot go wrong this way.
Installed the head unit and have power, when through the manual checking all the settings, turned off that annoying beep.
With Demo Mode disabled and ATT turned off, I cannot any sound from the speakers.
Tried Tuner, CD, iPhone via USB, SeriusXM via Aux In and NOTHING! No static no sound,
but the beeper beeps when enabled and the power off alarms sounds through the front speakers
when the head unit is turned off.
Disconnected the SubOut and remote amp wire and still no sound.
I'm at a lost now.
