Installing Sony Premium Sound in XLT
Long story short...
I got a really good deal on a Sony 700w Amp and sub from a 2011 Lariat.
Got a 6cd/sat unit w/sync
I installed the head unit, gps, and sync and got everything to work great
Bought all the pigtails and harnesses, followed the diagrams from the service dvd.
Turned it all on and....
Nothing.
In the Diagnosis and Testing section there is a section that reads as follows:
"When the ignition is in the START position, voltage is supplied to the Audio Control Module (ACM) through the START sense circuit. When the ACM receives this voltage, it mutes the speaker output by removing the enable voltage to the audio Digital Signal Processing (DSP) module. This prevents popping in the speakers as a result of voltage spikes during engine cranking.
If there is a short to voltage on the enable circuit, the ACM continuously mutes the audio output, resulting in no sound from all speakers."
I did a pin-out test and there is voltage to this pin with the ignition on of about .07 volts d/c
Anyone know how I can fix this?

Sound Sytems/Nav. Systems with these trucks is tricky at best. When I started talking to my local dealer about a Factory-Nav. install into my 2009 XLT, I was told that it would be more money than I'd be willing to spend, not just because of the Expense of the System, but because of the Computer and Wiring Overhaul that would have to be done. Yes, I did say that...the computer. It would seem that even the computer is pre-configured for the build of each truck(Overall circutry configurations I'm assuming when it comes to all required options). This is why you'll always see the Factory Navigation Paired with the HVAC....the computer is Designed to see it in that configuration. A similar comparison would be the newer Chinese "OEM-Style" Navigation units. They'll work great on the Standard package trucks, but once you move up to a truck that has had a Sony System in it or Factory-Nav, the head-unit will not work properly
Now that you've already taken the plunge with the sony...I sure do hope it works out for you....While the SonySound isn't going to be as complicated as a Navigation attempt, it will take a creative workaround just the same I'm sure...Keep us posted....
