I had the same issues as many above. Took it in and they fixed it as per the latest TSB but now it works even worse then it did before...Very frustrating !

 

Mines worked perfectly since i got it back so i'm happy at the moment. Now if i could just get the back up camera lines to stay on

 

On a side note in regards to the bluetooth audio skipping / buffering...I read that if you disable the WiFi connection on your bluetooth device that will solve that problem...not sure if that is true or not but thougth I'd share

 

well i spoke to soon. Bluetooth is broken again but fortunately my phones screen shattered so i now am using a $15 go phone w/ no bluetooth so i will never notice

 

well just got a phone call from the dealership who "fixed" my truck. They said it was fixed and parts replaced and the paperwork says it was completed, the parts to fix it just arrived at the dealership so the week they had it they didn't do **** to it, lied to me and now expect me to drive 4 hours to them to do the same work again.

 

that sux....I hate it when dealers lie about repairs.....

 

I have the exact problem stated. No power to AUX channel when pressed, no "Sync" dialog when steering wheel phone button pressed. Dealer has been hard booting it, and then it goes down a few days later. This has happened 3 times to no avail...

 

been doing the same thing...and am tired of going to the dealer!

So what do we do now? Anyone know what it takes to put together some sort of class action suit or something, it's pretty frustrating...

 

Ever since the tsb was done for programming the ACM, my sync has worked flawlessly, and faster than I remember....

 

The easiest way to fix the issue...buy a new radio that has bluetooth. The one I recommend is the Pioneer AVH P4400bh. It's an outstanding radio and the bluetooth is great. No problems, plus if anything goes wrong Pioneer will fix it and not give you the run around.

 

This is the exact problem I am having and it looks like that TSB might be right on the Money..... I'm copying and pasting this info right to the dealer.

Here’s the text of the TSB:

TSB 11-10-22 SYNC LOCKUP DURING VEHICLE CRANKING / STARTING - SINGLE CD OR SIX DISC CD - BUILT ON OR BEFORE 7/29/2011

The article supersedes TSB 11-9-7 to update the Action statement.

ISSUE:
Some 2011 F-150 vehicles equipped with SYNC and either a single disc or six disc cd player audio control unit and built on or before 7/29/2011 may exhibit a lockup condition of the accessory protocol interface module (APIM) when the vehicle is started. This concern may be more evident with a USB device connected and/or with the door open.

ACTION:
Reprogram the audio control module (ACM) to the latest calibration using IDS release 75.04 and higher. This new calibration is not included in the VCM 2011.9 DVD.DVD. Calibration files may also be obtained at www.motorcraft.com.

Thanks for the bump, i'll schedule to drop my off (need other work done anyways) in a few weeks while i'll be out of town for work and hopefully have my sync system finally fixed.

 

Well, it's done. I had to tell the dealer that I wanted that TSB SPECIFICALLY Done, but the improvement is obvious. I get about 90% success rate when starting the truck that the phone connects to the Sync. Previously, it was about 40% or so.

The other issues I suspect are Sync related. When I hit the voice button, and choose "Services" it can take 5 minutes to connect. Not sure what it's doing. After that first time, it gets better.

 

ok, I just got back from the dealer and they told me that the ACM was bad and they have to order it... and about $500, does anyone know where is the ACM located?
