Is there a control head sync file for the APX series like there was for the ASTRO25 series mobiles? I've got a dash mount APX6500 that is showing FL 01/90 and then goes into maintenance mode. I am able to read/write to the radio through the rear accessory port. I even did a firmware refresh to 16.12 through the rear accessory port and still no luck on communication with the head. I am able to put the CH in flashzap mode manually and my computer recognizes the head. Just wondered if there was a sync file I could try before I send this off to the depot.

Just out of curiosity, what control head are you using and is the radio an "Li" model? (If so, it'll only with with an O2, O3, and O5 head...no O7 or O9 support in "Lite" models)

Sorry, should have mentioned that in my original post. It's not an LI model. Using an O5 head. Radio has been installed in a squad car for about 6 months with no issues. Went to the city garage for an oil change and came back with FL 01-90 error.

APX mobiles automatically upload the appropriate control head firmware when the head is plugged into the radio for the first time if it is incompatible or out of date. You could try syncing it to an XTL5000, and then re-syncing it to the APX, but I'm going to guess the head is pooched. If you are getting an 01-90 error, the head is not seeing the drawer. Does the drawer have power?

That's what I kind of figured. I have even tried a known working flex and still a no go.

Yes, I power to the drawer. I'm able to program through the rear accessory port just fine and it even receives on the talk group it was left on when the vehicle was last shut off.

Have you tried another head or replacing the control cable?

The 01-90 error is telling you that the trunk unit isn't talking to the control head. Typically, the remote trunk portion doesn't have power on it. The control head does.

Yep, tried a known working O5 head from an XTL and still getting the same error. Off to the depot it goes. I'll report back what was wrong when it gets returned.

Since the error indicates the head is not talking to the radio and more than one head are doing it, I would suggest trying a different cable also. Probably not the issue but a lot easier than pulling it for repair.

Its a dash mount

I'm sure you already knew this but only black-face O5 heads will sync with an APX. Older gray-face heads will just sit there in maintenance mode and not suck down firmware from the brick.

Yep, it was a working black O5 head. Well, just got the radio back from the depot. Since the new computer system has been in effect, the paperwork I have been getting back with radios has been vague. The sheet I got back with the radio simply says "replaced accessory kit, APX. Performed complete PM"

Not sure what an APX accessory kit is?
