Had this same problem. Tried master reset, reformat, everything. I think the memory on some of these older APIMs are just starting to go. Put in a new one and all better. You can get the nav ones cheap off eBay.
Yep, no space left in rwdata folder. Normally, since you do not have a MY20 APIM, you would just perform a reformat and install the same version you are at, or other if you like. This would fix the issue. However, to use the reformat tool you need to downgrade, which you cannot do (VER_ERR08 error).
I was able to downgrade eventually despite the ver_err08. I created a forced downgrade stick with only the app. After a few consecutive master and soft resets, it worked. I suggest to keep on trying to downgrade. I remember that when the problems first occured two weeks ago, a reinstall of 22251 worked after many tries. An educated guess here would be that a certain number of resets clears up just enough free space. It also only worked when I tried to install the apps, nothing else, no voice, no nav.
Forced downgrade. I was trying to remember how you did that. Thanks.
There is a reset procedure for Sync of doing 2 reboots in a row, right after the other, that can clear errors. It works for the BGMAP errors and a few others. I do not know if it will work in this case though.
I made two master resets in a row as suggested and successfully downgraded to 3.3 (forced downgrade only app file). thanks for suggestions.
now I’m going to install 3.4 22200 in reformat mode.
Hey @tomasbut , it would be nice for you to keep on eye on that partition in about a month or two… If this is a particular issue with a build, since you have installed a different one, should not increase.
I am getting the VER_ERR08 error when trying to downgrade (after the SYNC 3.4 build 22251 update-resetting each time I power off the truck)- I don’t understand how Ford cannot take responsibility for this with so many people experiencing the same issue shortly after the update they provided.
My rwdata folder is full. I am pre My20 and willing to risk just about anything at this point.
Is there a way to free up some space in rwdata?
Thanks SaNdMan, I’ve been trying all the suggested procedures to no avail. I assume they are referring to the Master Reset in the sync menu. I will run through a few more times as it seems to be hit and miss.
I would expect a reformat to be just that, so I’m a little perplexed as to why I get a ver_err08 error when trying to “remove files” through a reformat, if that is in fact what a reformat is doing-referencing my IT experience here.
I am new to this forum, so I may find more things to try as I dig.
Reformat is not master reset nor does “remove files”. Reformat does what the name says: reformats the unit, thus erasing EVERYTHING on the unit, even installed packages (yes, that includes the OS, maps, rwdata partition)… unit won’t be operative again until the reformat phase is completed
Going back to an older Sync3 version is required since the reformat tool has been blacklisted in most 3.4 builds
You need to reformat the unit in order to erase the rwdata partition… this is actually a “half-true” statement, since you are not just deleting the rwdata partition, you are starting everything from scratch.
Once you manage to downgrade to another build where the reformat tool is permitted, you should be good to go to fully reformat your unit with the desired version.
Perform a soft reset 2 times in a row as described above.

Thanks everyone for your help: Here’s what worked for me.
My master reset would hang, so I used forscan to reset the APIM a couple of times. then was able to do a normal Master Reset a couple of times from the touch screen. Ran the interrogator and discovered I now had some free space in the rwdata folder. Created a downgrade USB stick to version 3.3.19052. Finally was able to complete the downgrade. Updated with format option to to 3.4.22200. Ran interrogator and now have 781M free space. Disabled Auto update!! So far everything is back to normal.
I’m in Canada and you all just saved me $1000 for a new APIM.
