My ACM has just stopped working. The unit doesn't know my ipod is connected anymore. I've pushed some ON/OFF button on the ACM itself ..still nothing..

What should I check?

Thanks!!

 

there is an update you can do. when did you have it installed? (or when did you install it yourself)

I forget the webpage, but basically you download something to a USB stick,,, and then plug it in to the car and it fixes things...

TECHS???

 

I got in in...June I think. I may have one of the older ones as there is no place for a USB stick.

 

strange, I thought all acms come with RCA, and USB jacks.. and the IPOD one.

did you install it?

 

No, the dealer did. It has RCA jacks!

 

What year is your car? Is the Ipod fully charged? Is it a new ipod or one you have been using for a while with no trouble?

 

04 X. Yes it's charged and I've used it for a while.... BUT... Here is the weird part:

1. It's working again.

2. Around....September, the radio would wait...ten seconds after powering, losing it's bass/tremb/seperation settings. No rhyme or reason. 7 times out of ten. Sometimes it would come on just fine.

3. Around...October, sometimes it wouldn't come on at all.

4. This month...it stopped doing all of that, but my ipod would go off shuffle (where I keep it) and move into alphabetical list.

5. This afternoon it couldn't find it...just got back from dinner and it's working just fine.

Am I....haunted? Could this be the ACM? The unit head?

 

movin it back up

 

here's the thing. the ACM should have an iPod connection, USB, and RCA's. If yours does not have all 3 then the dealer did not install it correctly and I would have to guess that they might have messed up the whole thing. Did the car come with it or did the dealer install it after you get the car?

 

After I got the car. There the ipod connection...the RCA plugs, and a cable with an odd looking connector on the end of it.

 

ACM HACK
I installed an ACM in my ´07 S-Type and love it, but the ACM loses contact with the car stereo once or twice a month. There is a tiny reset button that can be pushed by inserting a paperclip or such into a hole in a side of the ACM unit (with RCA connectors) that is accessible in the glove box.
Since that is ungainly while driving, and since I don't own a CDC, I re-wired the ACM unit in the glove box so that the toggle switch, called "CD Changer Bypass Switch" in the ACM documentation, is re-used as a manual reset. Crude, but effective.
When the ACM loses it, I flip the switch toward the back seat for 10sec and then forward and after 3sec, pushing the CDC button on the radio enables the external audio again.
You need a soldering iron.
If anyone is interested, I'll share the details.
In the meantime, thanks for the tip about a USB update that might be a solution for the same problem. I'll look for that now.
